The only two that stand out in my mind are MOUSEHUNT and PIRATE RADIO.
MOUSEHUNT because I was a kid when it first came out, and it was a movie that my parents were really anxious to see... when you're a kid, and your parents want to see something, you automatically assume it's some kind of a boring, talky, sleep-inducing movie (remember when I was in day care and our teacher took us to see that John Travolta movie PHENOMENON?) However, I loved it; it's a really funny and excellent live action family (for the most part) movie.
PIRATE RADIO, I didn't necessarily believe I would hate it, but I had a feeling that the story of the rogue pirate radio station would take a back seat to an amalgam of the kind of amoral behavior that people of the 60s engaged in, but it did turn out to be the other way around: yes, there's sex and drugs and such in the movie, but the main focus is indeed the radio station and the quirky lot that run it.
