Okay, so I finally saw this last night. I'd read the rave reviews, but I was still not prepared for it to be this fricking good. James McAvoy completely kills it as young Xavier.
I don't even know what to say, I just want to go see it again.
I see people pointing out continuity errors and plot holes, but I'm just like... I feel this film actually ties all the other ones together, including the original trilogy. Great, great stuff - it has definitely made me all hyped up about X-Men again, it's been a while!
