If it isn’t apparent yet, I cannot say enough good things about this book. It is exactly the beginning we needed to a new era in Journey into Mystery. Not to be hyperbolic, but if you fail to give this first issue a chance, then you don’t like comic books. It’s that simple. This is story telling of the highest quality and art like you won’t see in any other Marvel titles to say the least. Give it a shot. For Asgard. Read Full Review

This is an exciting time for this series because existing readers should appreciate the change in character and direction, especially since Gillen and Kid Loki return in next years Young Avengers. But newcomers to the series may also find something that they like and want to stick around for and that is truly exciting. If you're into the whole Asgardian mythology thing, warriors and warrioresses, and a story with a phenomenal female lead, then this is certainly the comic you need to go back to your LCS for. I'm very pleased with what this next creative team is doing with this title and I am excited for more! Read Full Review

Journey Into Mystery is the kind of thing Marvel wanted with their 'Point One' campaign many years ago, an accessible story in an already established series that can draw in new readers. This is the kind of comic that stands out from the rest of their comics both because of it's content and it's female protagonist. This could quickly become one of my favorite comics Marvel is currently making. Read Full Review

This isn't the Sif I've come to like and definitely not the Journey Into Mystery I've enjoyed. Read Full Review

For older readers, it's a good start to this five-part story - here's hoping for more of the same. Read Full Review

Journey Into Mystery lovers have a lot to be thankful for this holiday season. Gillen will be continuing the exploits of Loki in Young Avengers next year. And meanwhile, the series itself is in capable new hands, with Immomnen's first issue suggesting her run will only get better from here. Read Full Review

This issue does a great job setting up who Sif is and what her motivations will be in this series. It is also paired with some truly breathtaking artwork which you definitely will not want to miss. Overall, this is a great first issue for anyone who is curious about Sif, or for someone who is looking for something new to read. This first issue of her arc is definitely worth a look. Read Full Review

Overall, what's most impressive is that Immonen and Schiti have created a journey for Sif in this first issue that feels both epic and also extremely personal. The story ends on a particularly compelling note, one that leaves me anxious for the next installment, and with this creative team at the helm, I'm excited to see what's next. Read Full Review

Valerio Schiti's art is a good match for Immonen's work. He adopts an angular but flowing style for the action-oriented sequences that reminds me of David Lafuente's kinetic style from the afore-mentioned Hellcat series. But for the quieter, conversational scenes, there's a softer look at play, notably in the characters' features. Furthermore, consummate Thor artist Walt Simonson's influence quietly looms over the whole book. It shows through in Sif's general look and is even more apparent in the design for the corpse-eating dragon the heroine seeks out in the second act. Read Full Review

Without giving too much away, that's Sif undergoing something of a transformation. It's a shocking direction, one that might spell a departure from all I've said of the character's behavior up to this point. In the end, I suspect it might bolster that characterization. Until then, Sif's going to display a whole new attitude. Read Full Review

Overall, the series is in good hands. I am confident that Sif will be more than able to carry the title until her story is done. The question now is will people who have never read this book give it a chance? Well, with all the talk lately of the supposed lack of female characters having their own books going on these days, I hope people will be willing to put their money where their mouths are and give this book a chance. It certainly deserves to be looked at. Read Full Review

Journey Into Mystery has taken another new direction and once again it works, Lady Sif is a character who hasn't really had a chance to shine as much as her ex-love and his brother. So it is nice to see her get the spotlight as she proves in issue one that she carry her own title. Good introduction and good art for another strong NOW! title, recommended. Read Full Review

While there are a few stumbles along the way, this issue proves itself a solid and enjoyable introduction to Sifs adventures in Marvel NOW. Read Full Review

Even though the issue stumbled a little when it got to the meat and potatoes of the first arc, Immonen so clearly has a great grasp on these characters already and knows how to entertain a reader. This is a title that is sure to exist with a lower profile among the rest of the Marvel NOW! launches, but because of a strong focus on character and some beautiful work by Schiti, it deserves to be noticed. Hopefully, it will be. Read Full Review

For those hoping that Journey Into Mystery would transcend its sleeper status, well, you'll probably have to think again " and to be honest, Immonen and Schiti probably have an even more uphill battle to climb than Kieron Gillen did with Loki, given that Sif doesn't have the mischievousness, the cuteness or the billion-dollar movie behind her that the God of Mischief did. But there's a nice gung-ho girl-power spirit here, following in the footsteps of Kelly Sue DeConnick and Captain Marvel, and with some truly effective art, there's no telling to what heights this Journey Into Mystery might take us.

The retooled Journey Into Mystery #646 offers a promising start to a new era of Thor-related fantasy adventure comics, with Valerio Schitti drawing beautiful images of monsters Sif hitting things, Immonen writing jokes and offering a very promising set-up to the current story arc. Looks like the warrior goddess is getting a bit bloodthirsty. Loving Sif's new costume, too. Read Full Review

So, as a first issue it sets up everything you need to know about Lady Sif and the plot. But the narrative lacks weight and seems to have a limited scope to what can happen going forward. The characterisation is there and if Immonen keeps it up Lady Sif might be able to become a character in her own right as opposed to being Thor's other girlfriend. But she may need a stronger story than the one presented here to help her develop her appeal to new readers. Schiti's art suits the material and he gives Sif a distinct look that captures her character perfectly, but it is Bellaire's colours that give the book a beautiful visual identity. It is too early to tell if Sif can sustain a book by herself, but this issue is a step in the right direction. Read Full Review

Early on, I was critical of Marvel NOW not renumbering some of its female-centered title launches to benefit from the massive sales opportunity the program could provide. Now, Im fairly certain that was a wise choice. This is definitely not a jumping-on point for the uninitiated. A new #1 would have been much more misleading than the marketing already was for this title. Read Full Review
