I don't think lying has any ultimate justification. I don't think it ever leads to anything positive. The good fight to have is not to lie. That's one of the challenges in a way.
There's good movies and there's bad movies. The genres are never dead, it's just about how to apply them and articulate them and execute them - the story, the quality of the writing, the acting, the design elements, the directorial execution - all these things make it what it is.
