Mario bros - I hated this movie when I saw it back when it was released. As a pretty big Nintendo fanboi I found it a huge slap in the face. Rewatched it a few years back and found it very enjoyable. Bob Hoskins, John leguismo and Dennis hopper Are fantastic in this. It's got unique setting, cheesy humour and keeps it light hearted. I think it's a lot of fun.
Ghostbusters 2 - this one Mystifys me on its hate. It's legit good in all ways. Fantastic cast, extremely quotable, great humour and some fantastic set pieces. The fx were fantastic for there time and completely hold up. Peter fucking McNicol is all kinds of awesome. HE IS VIGO!
Alien 3 directors cut - even before the very well received directors cut I really liked this movie. Fantastic British cast! Charles s. Dutton gives these fantastic speeches and completely owns every scene he is in. Charles dance is the soft spoken love interest for ripley. The directors cut adds a lot of extra scenes and even changes what the face hugger infects. It vastly improves the movie.
