Critics and film industry experts have already written everything about that movie and it's possible that you have heard every interpretation and opinion there is. That is why I will only add two discussion points:
1. Is Chateau Marmont, legendary LA hotel, really so not- luxury-at-all inside? Is stories form the past and old, used furnitures really all there is?
2. Where is Stephen going in the last scene? And would you really leave your Ferrari by the side of the road?
