It's a man. He's invisible. He's doing bad stuff. What else is there? It's a horror movie about an Invisible Man. Why adapt the original story again? The original already did it so well, and Hollow Man updated the basic concept as a modern techno thriller two decades ago, so that's already taken.
His last name is even Griffin, and there's a nice little visual callback a quarter of the way through the movie where Elisabeth Moss's character is in the hospital and looks at a burn victim's bandaged face that doesn't quite make sense in-story but the audience understands is a visual Illusion to the original movie and Claude Rains bandaged face.
It's suspenseful, has a few really cool action scenes, some gasp-ilnducing twists and turns, the cast does a great job. It's just a good movie. Mind you, I think the director's last film, Upgrade, was just about a modern classic. This one isn't quite as good as that one, but I love that he's getting some success here.
