I’m generally sick of remakes and relaunches and reboots — it seems borderline obscene that it only took 10 years for Sam Raimi’s awesome Spider-Man movies to get kicked to the curb in favor of new blood — but this revamped X-Men origin story is kind of fun. Set a couple of generations ago, when fear of the Cold War still cast a long shadow over the swinging 60s and memories of the Holocaust still festered like an open wound, it’s a period piece into which has been injected a tale of two mutants.
