Interesting that some of my all time favorite movies are on some people's "worst list". Just no accounting for taste. Among the "worst" that are my "best":
Being John Malkovich
Being There (I loved Peter Sellers in this)
Punch Drunk Love (the only redeaming thing Adam Sandler has done, IMO)
Attack of the Killer Tomatoes - one of those cult films
Starship Troopers - great parody of sci-fi action films
What movies are you embarrassed to admit you like? Care to own up?
For me, the all time most shameful movie I will admit to loving: Ishtar! Every time Warren and Dustin sing one of those awful songs, I just roll on the floor laughing.
