Bryan Singer’s X-Men movies are somewhat faithful to the comics but really botch some character arcs. Everything got further butchered with Brett Ratner’s The Last Stand, which somehow made The Dark Phoenix Saga into a boring mess. I believe First Class to be the best of all the X-Men movies (go back and re-visit the first two films- they don’t hold up so well), and so I was excited to see what would happen in Days of Future Past, one of the best X-Men stories.
For the most part, I was relatively bored. Singer had a chance to retcon some things (like the fetish leather outfits), but his dark future takes mundane darkness to the extreme. The assembled cast is all sorts of impressive, but save James McAvoy, no one gets much of an arc (notice a theme here?). I think after this film, I’m done with the series, regardless of how Apocalypse turns out.
