Ok, I'll play. My favorites are:
1. Enchanted April
2. The Princess Bride
4. Monsoon Bride
5. My Big Fat Greek Wedding
There are way too many to list as worst. Any Friday the 13th or other slasher flick, most anything mainstream Hollywood puts out these days. I really dislike blood and gore, you'll never catch me watching it. Also I don't much care for war flicks, other than The Bridge On The River Kwai and most John Wayne movies. No Full Metal Jacket or The Deer Hunter for me. I know it happened, I just don't want it in my living room.
I'm an indie film buff. I do love that Overboard, though, it's such a happy film.
