Just watched X-Men: First Class. I don't understand what the hubbub was. I thought it was worse than X3.
The set and costumes are a wreck of occasional, half-hearted waves at 1962. The script is a mess. It's basically the same story as the first X-Men movie, for one thing. For another, the only decent line of dialog is "Turn the nuclear reactor to 100% and see that I'm not disturbed." Except for the BabyMutants! scenes, the first 25 minutes is promising, and then Moira MacTaggart gets completely lost. The vague love quadrangle is awful, as is the TeenMutantDanceParty! sequence.
January Jones is terrible. Jennifer Lawrence is an embarrassment, and she's taking over from a fashion model. Think of that: a fashion model was more menacing and emotive. Michael Fassbender is great until he drops all pretense at an accent and turns into the Lucky Charms leprechaun at the end.
Also, the Cinemax Dish Network rating clearly promised N and SC, and there was no N or SC.
