Just as there are video games based on movies, there have also been a great deal of movies that were based on video games. So, I want to invite people to weigh on on what, in their opinion, what was the worst ever movie that was based on a video game, and if you like, the reason behind it.
For me, I'd have to say one of the overall worst was Super Mario Bros. I'd say watch the movie to see why it was so bad, but I'd rather not subject anyone to that.
