Teenage Mutant Ninja Turtles. By which I mean TMNT 2: Secret of the Ooze. I do NOT mean the 3rd one, which was not that great.
Dude, TMNT 2 had Vanilla Ice and a plot to defeat enemies with DONUTS and other awesome things. It did not however have Casey Jones, although he was in movies 1 and 3. In any case, TMNT 2 is my all time favorite Ninja Turtles movie.
Another one? Evil Dead 2. Mostly because Evil Dead was not that great. But Army of Darkness was the best of all 3. It is one rare occurrence of each movie being better than the last.
