Number one: Twilight. Yes, not a very creative answer, but I gave it a chance. Not many people did that. I gave it a chance, and in return, it filled me with utter disgust. Not anger, not hatred, just disgust.
Number 2: The "Twilight Zone" movie. It was probably a lot worse for me because I am a huge fan of the original Twilight Zone series, and the movie just kind of took a crap on the entire show. I guess I can't blame them, considering that Rod Serling is dead (but not dead in our hearts), and releasing a movie in black and white these days is almost unheard of, but I like the way a man on youtube put it:
"The Twilight Zone in color is like porn where the women are all fully clothed"
