The Percy Jackson shit and any bad book adaption. The last airbender. Star Wars I and II. Ghost rider spirit of vengeance. These are just the ones that come to mind, i have seen countless bad movies i probably repressed, don't make me remember.
Probably some of the movies that I had to make with a bunch of people as a class project in school. I heard afterwards that especially one of them was so terrible that the teacher used it as example of thing that you should avoid and not do while making a movie. It was really, really bad....
What made it terroble then? Because a bunch of brats who had no skill or knowledge about anything decided to do a movie. To this day I don't really understand what the "plot" of the movie was, if we even had one.
I would like to say The Last Airbender too, but since I have only seen Nostalgia Critics review about it and not the actual thing, I think that does not count. Next on the list is probably The Happening from the same guy. Watched it with my sisters and everything that was supposed to be scary made us laugh. This video summs up it pretty well too: https://m.youtube.com/watch?v=HVwtCU48Koo&feature=youtu.be
Wow, lots of last airbender's. I didn't even think it was that bad considering some of the horror stories about other films I've heard about.
For me, it's Tentacolino or The Garbage Pail Kids. Lackluster animation, a terrible, insulting, brain-dead plot, and the worst soundtrack to any other film that I have heard in a while for Tentacolino. As for the Garbage Pail Kids... everything you've heard is true. It's so hard to watch. For me personally, I shut off Tentacolino in 40 minutes and The Garbage Pail Kids in 20 minutes. Tentacolino I shut off right after the song number with Pingo or Pongo or whatever, The Garbage Pail Kids after they unscrew the pipe and dump the sewage all over the main character kid. Neither of them I've been able to finish all of the way through to this very day.
Foodfight! is a close third, only I actually finished Foodfight! all of the way through. Not saying it wasn't bad, though. It was terrible. I just somehow came out the other end alright (probably because I watched it with my little brother and we heckled it the whole time).
