Worst of Christopher Nolan. The film seems fascinating but if you've watched Interstellar and inception kinda films, then you might not like it. The way he has set his standard in si-fi, does not met here.
Acting/cast : 5/5
Plot : 5/5
But when it comes to the concepts, "you are changing the rules/concepts in one scene and the other. "
Changing the concepts was worst.
