Where to start...there's so much to like here. Having read Vol. 4 right after this one though, I think this might be the peak of the series. That's not a knock on Vol. 4, but rather, a compliment to just how well Bendis has written each and every character here. The interactions, the personalities, the sheer humanity and humour, love, anger, they're all here on display, and they all feel authentic. I BELIEVE this. I believe in why these people are doing what they're doing, acting how they're acting, and saying what they're saying. That's no easy task these days in the comic world.
We left Vol. 2 on a cliffhanger, with one of the Original X-Men about to join up with modern Cyclops and his band of outlaws. This picks right up there, and there's a huge commotion about it. When you think about where the modern equivalents of the original 5 end up, you won't have a hard time figuring out which one says forget this, I'm flying off with this guy.
The part I love is that people have normal responses to this, including Teenaged Jean Grey having a hissy fit, which, when you're a powerful psychic, can be very bad. I like this new characterization of Jean as a teen girl who has too much power and cannot control it, and who has other issues to deal with at the same time. We also see a lot of signs that this Jean Grey isn't Prof. X's prized student; this one has a lot to learn, but thinks her powers are going to let her do what she wants. When Magneto makes more sense than you, odds are, something is wrong.
PS. Stuart Immonen has made Cyclops and Magneto look BADASS. Magneto looks like a cross between Boba Fett and a Cylon, while retaining his Magneto-ness (?) and Scott has the wardrobe that finally makes him look as dangerous as he actually can be (and is).
I also like the role Kitty has taken on as the mentor (Prof. K to her X-Men kids) it's a great thing to do with a character who wasn't having a ton to do other than run the school alongside Wolverine.
Then the side story that moves events forward (but isn't really that important, I will grant) has Mystique, Sabretooth and Mastermind (the daughter) stealing a buttload of money from Tony Stark, and posing as the Original X-Men. This leads to a run in with the Uncanny Avengers...
This provides some of the best stuff of the volume, with a young Scott Summers running into his much older brother Alex (Havok). Seeing as how the grown up Summers Bros. don't talk much, this is a chance to see Alex be happy with meeting the best version of his brother that there is. It's also fun to see Cap being pissed off and wanting to deal with problems, only to have Thor and Wanda tell him 'It's a brother thing, let it go.'
I feel like there's a good balance of the 4 originals here (with the one departed no longer involved). We get to see a new development of romances that hadn't happened before, and we get to see someone's sense of humour is still intact. (I especially loved where Iceman throws a snowball at Thor to see if it's the real one, and says "OOO Mr. Thor Sir, I am SOOO Sorry!" in deep fear that he's just hit the Norse God of Thunder with an snowball upside the head.)
Bendis ranges from humour to gravitas, to love, to anger, and they all feel right. I can accept a book with a minor action plot when it involves a lot of great character development, and the bits of action we do see are all impressive anyhow. I won't keep gushing, but I really enjoyed this book; I think it's 4.5 stars, but I pushed it up to 5 just because.
Vol. 4 is coming next, and having already read it, it is solid too, but not quite up to this level.
