Iron Man 3 - Not the fanfic you wrote in your head for the movie, but if you can be an adult and get past that and are capable of feeling joy then its incredibly fun.
Wait a second, watching bad movies on purpose so you can rant about them? Oh brother, you're on my territory now. I do that once a week already. I could recommend some true madness to watch. Trust me, as bad as Atlas Shrugged Part 1 is, Part 2 is a masterpiece of hilariously bad cinema. If you ever want to team up and do these as an audio feature, I am totally down for that.
