The Postman with Kevin Costner. This is without a doubt the worst movie ever made. I know there are a lot of bad movies but usually they're supposed to be bad. I can't help but feel that The Postman was really trying to be good.
I am a huge fan of post apocalyptic films however the Postman is unwatchable. My roommates and I sat around hung over/drinking one morning and it came on. We all died of laughter at how unexplainably bad it was.
If you have not had the opportunity to watch this film, please do. You will walk away with asking so many questions about the 36,000 plot holes.
Good luck
