My absolute favorite #1 watch-it-all-the-time popcorn movie is
"SCREAM". It's not really at all scary, which is really why it's so charming. Just an incredibly entertaining, well-done pseudo-comedy.
Other favorites are the original "Nightmare on Elm Street" and "Friday the 13th" -- great party movies
...of course it could just be the fact that "Scream" has cute Matthew Lillard, "Nightmare on Elm Street" has cute young Johnny Depp, and "Friday the 13th" has cute young Kevin Bacon...
Arigato,
