Jeff the Land Shark is Marvel's most successful fully new character since Deadpool, which you could regard as a terrible judgment on their publishing strategy and/or the superhero marketplace – but set against that, he is really cute. First appearing as a sidekick, he got spun off into sweet little gag strips and now stars in a full sequential story of his own, though let's be clear, this is no attempt to go epic and explore deeper issues in a Shark Knight Returns. Rather, Jeff gets into yet another ridiculous scrape – his shadow comes to life! – and then, chasing the demon responsible, plunges through a series of portals so that he can have team-ups with other characters the kids like (Deadpool again, Rocket & Groot) or should like (Elsa Bloodstone!), face off with dinosaurs, borrow Wolverine's claws for a bit... If you're looking for rigorous plotting, this is not the comic for you, and also, never try watching a Looney Tune. I don't just mean at the level of individual incident (does it make sense that Rogue can translate for Jeff after giving him a forehead kiss? Not really, but it means we can see a cute lil' guy getting a forehead kiss), but in terms of the overall notion that Jeff is pursuing the shadow demon because his good boy reputation is at stake; surely everyone knows he's a good boy in the inherent sense that's unaffected by surface details like his frequently being an absolute menace? None of which matters a jot, because this is adorable fluff and doesn't pretend to be anything else.

Thanks to Edelweiss and the publisher for providing a DRC of this book in exchange for a honest review.

IT'S JEFF! Jeffy Jefferson Jeffrey, my cute shark-dog thingy. Love that lil' dude. This comic is infinitely more enjoyable if you're a Marvel Rivals player, as it heavily features cameos of characters playable in-game. Regular Marvel comics readers may also enjoy this collected edition of Jeff's adventures, although with the caveat that this is aimed at younger readers and/or readers who like a cute, lighthearted romp. Anyone looking for a complex plot and psychological depth will probably want to pass on this one, but on the other hand, if you enjoy a dash of smartassy quips with your dialogues, this one has its moments (special love for the Deadpool as well as Groot & Rocket cameos on that note).

On a sidenote, I tried reading this on my (admittedly small at 6") kobo and promptly gave up due to the tiny text and time it took to zoom on everything to spare my eyes. I ended up reading the rest of the story on my laptop, and therefore I'd recommend either picking up a physical copy or making sure your screen's size is big enough to read the text comfortably, otherwise it will impact your reading experience negatively.

Adorable, if a bit frenetic. Each issue has Jeff pinballing across the Marvel Universe into a different character's lap as he attempts to track down a demon that's stolen his shadow. Things move at a breakneck pace, and while that's fun, it does mean that we don't really get a moment to breathe. It's a very 'everyone and the kitchen sink' approach, to the point that when everyone turns back up again at the end to help with the final 'battle', there's barely enough room on the pages for them all.

Still, the little guy remains the cutest thing going, the artwork's great, and I was also amused by the in continuity nods to certain things as well. Comedy books like this often get put into their own little side bubble, but Jeff has remained firmly in the main Marvel Universe spotlight.

5/5 stars for a fun and flippant little romp through the Marvel Universe(s) with Jeff the land shark and all his pals!

It's no more and no less than what the cover promises and past Jeff adventures have delivered-whimsy with some superheroic action centered on the cutest land shark since ever.

Thanks to Edelweiss+ and the publisher for access to an advance digital copy for the purpose of an honest review!

My daughter and I love reading It's Jeff together. I'm so glad that he got his own series but I prefer the Infinity Comics stories available through Marvel Unlimited. Read as individual comics, ratings below:

#1= 3 stars
#2= 2 stars
#3= 3 stars
#4= 3 stars
#5= 2 stars

Overall rating of 2.5 stars

It's finally happened.
Jeff get his own full length feature film comic book.

In typical Jeffrey the Landshark fashion the vibes are set to "Fun" and the story and art reflect that.
Tokitokoro's art is whimsical and suits the shenanigans Jeff gets into.

All sorts of fun cameos help the story be more then just his little One Shot adventures, while still retaining that feel.

Read the single issues on marvel unlimited. Jeff stories are so cute and silly. He should get to do a “kills the marvel universe”
