Do you ever find yourself trying to convince people to go see movies that are tanking at the box office? Or saying, "Just give this movie a chance! It might be bleeding money right now but it really doesn't suck!"

If you answered yes to either of those questions, then this list is for you. We define "flops" as films that didn't perform as well as expected or just flat-out lost money in theaters. And we define "great movies" as those films that were critically praised or adored by audiences or both! You know the ones, the cult classics and underrated gems.
