The second Superman (original) is pretty terrible, but the director's cut is noticeably better. I like X-Men 3, Alien 3, and 4 better than most. Godfather 3 is okay. The first Star Trek (original) is very weak, but the second is nearly perfect. The second Die Hard is really corny but tolerable. The third Die Hard is a big improvement. The second Planet of the Apes (original) is horrible, but the third is a big improvement.
