“You shouldn’t have brought me here,” says Magneto (Michael Fassbender), after the sinister Apocalypse brings him to Auschwitz. He has a point! It’s one of many scenes that could have been trimmed in a long, long movie with at least four too many central characters. (“Oh, I forgot about them,” I said aloud more than once.) This movie assumes a lot of prior knowledge from the audience – I barely remembered CIA agent Moira MacTaggert (Rose Byrne) from the one movie she appeared in five summers ago – but somehow the set-up takes about an hour and a half, anyway, making detours to both ancient Egypt and East Germany. Jennifer Lawrence’s screen time clearly got bumped up for contractual (rather than plot-dependent) reasons, just as Halle Berry’s did after she won her Oscar all those years ago. This time around, that’s not such a bad thing.
