good back-story, and good acting

Instead, you get a movie that's enjoyable enough, but leaves you feeling like it could have been much, much more.

The performances transcend the film's tropes, grounding it in characters that feel more complete than this subgenre often produces.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.
