re: .

1) Battlefield Earth-only movie I walked out of the theatre. I was with a friend who worked there, it was free, I knew it was supposed to be bad but it still made me walk out.
2) The Happening-I still defeneded Shamaylan until this one. I even thought the Village was ok. This was a disaster
3) Batman Forever-worse than Batman and Robin for me, there is nothing redeeming about it and at least I can laugh at B&R
4) Red Dawn (the original)-I am saying this only because I only watched it for the first time a few years ago. It was hyped beyond recognition by several friends of mine and I was bored throughout the entire thing. I enjoy 80s cheese and defend the one's I saw back in the day.
5) All of these ensemble cast Rom-Coms over the last few years. My wife likes them, I despise them. New Years Eve, Valentines Day, He Just Not That Into You, etc.

I don't see many bad movies. I carefully select what I spend my time on. I've seen the Room, Plan 9 etc but those are comically enjoyable with friends.

As a huge Coen Bros fan I do need to point out that I found Burn After Reading to be horrible.
