well it's not bad. it's pretty much what i predicted(91/110) and i didn't feel like it would be a flop. most people predicted something similar too. it only seems unimpressive cause we hyped ourselves up.
the way i see it:
this is the best reviewed cbm yet among top critics.
it has a huge increase of first class and wolverine, particularly os.
singer is 3/4 for great x-men movies(counting first class which he produced).
matthew vaughn is hopefully waiting in the wings to take on solo movies.
the cast is amazing, and a new storm, cyclops, and jean are waiting to be cast, so it's only going to get better.
overall i'm optimistic.
