My idea of a good movie is all about fantasy. Things that don't happen in real life but happen in movies, like people having special powers or something from out of the ordinary happens that wouldn't really happen in the real world.
I like to imagine myself in their places and see how cool it might be to be like that. Imagination is the key. The more a movie makes me imagine good things is the more I like about it.
