If anyone is wondering why X-Men and X2 are so low, it is because they really have not aged well at all, especially when compared to a movie like First Class that actually embraces its comic movie roots. X-Men was a great movie in the pre-Avengers era. But now,Singer's whole "I need to make it super realistic, down to Earth, and non-comic booky or audiences won't respond" justification to X-Men and X2 feels shortsighted and cowardly. It also makes the movies feel incredibly safe and boring in retrospect.
