I agree with everyone saying the kids were unnecessary, it detracts from the main story (bringing Laura to safety), dilutes the dramatic tension at the end of the movie between too many characters, and introduces lots of special powers... which generally means more plot holes in superhero movies as it's really hard to properly juggle lots of different powers in a scene without making a mess out of everything, which definitely happens here. The end of the movie suffers from the "let's show this guy's power" syndrome generally found in X-men/Avengers movies, which means you show the character's power... and then it's never really used in a meaningful way again. Cool moment maybe, but it doesn't serve the story really.
That being said, I thought the movie was fantastic regardless, mainly because of the main trio. I mean, the writers are obviously to be credited here, but the main trio just sell their characters flawlessly, so from that point on, the rest is just gravy. I love the small surprises the movie has in store for us, sometimes cutting out of scenes at weird moments, or how a few characters had sudden things happening to them (the antagonist at first who gets shot, Charles who gets stabbed out of nowhere, among others)
Dafne Keen is a revelation, although I wish her powers had been more different. Kid just rocks.
And will someone please tell me how they filmed all those acrobatics? It can't possibly be Dafne herself! I mean I just saw yesterday a kid doing that kinda stuff in The Enforcer, a chinese movie featuring Jet Li, but that was a Chinese movie, and he was famous for being a black belt at 8 years old. Kids usually aren't martial arts pro in the USA, so that was most likely a double.
The fight sequences at the beginning were really awesome, I want more of that in Western movies!
Anyway, great movie, loved the feeling of dread you get throughout the movie, ending is a bit sloppy but nothing too important.
2nd favorite fox-marvel movie for me (behind DOFP, which is my all-time favorite superhero movie).

edit: Fuck me multi-sideways, Dafne Keen is a martial arts, tumbling, and acrobatics expert and did her own flips
