General

I would like to include "Flash Gordon" in this list

I would probably say that "Torque" is a good example of this. Yes, the movie is cheesy and bad, but I like the movie for some odd reason. It pokes fun at "The Fast and The Furious" franchise, which I do actually like. The movie doesn't take itself that seriously.

Another example of a movie that I like and can admit is bad is "The Marine" starring John Cena. I can watch that movie and enjoy it, not to mention laugh at it. When someone talks about how bad it is, I won't argue with them about it.

I haven't seen this to be honest, but there's absolutely no way that it isn't just fantastically bad.
