Brett Ratner's damage has been undone

Rating: 10/10 (23 May 2014)

Like others have said, I think everyone is struggling to find something wrong with the film.
With the future being changed, it also changed the past. Jean Grey returns, and she never killed Scott, was killed by Wolverine. Any of the damage Brett Ratner caused in Last Stand seems to have gone after this.
Quicksilver was hilarious (but slightly annoying), and Blink's teleport portals were really cool, and I particularly liked the slingshot of Colossus in a Portal style.
I was disappointed not to see more than the one scene (showed most of it in the end credit scene of Captain America: The Winter Soldier) of Havoc (Alex Summers). I don't know why Anna Pacquin was in the credits, she had a 5 second non-speaking role at the very end of the film, mainly just to show she was alive. Also some people in the cinema were asking how Xavier was alive. It is explained in the comics, and we know it happens in the film because of the end credit scene in Last Stand, but it is never explained in this film, which I was surprised by. Plus, I did notice when James McAvoy's Xavier was looking into Wolverine's mind, it would swap from 1 finger on Wolverine's temple to two between shots. Happened multiple times. But again, this is all nitpicking.
Absolutely brilliant film, really enjoyable to watch.
What we are left questioning? What the hell was that end credit scene? Where will they go from here? Something that bothered me from the trailer: if Xavier transferred himself into his brain dead twin brother's body, why was he still in a wheelchair if his brother never got shot on the beach like he did?
