Christopher Nolan has a pretty good track record. His Dark Knight trilogy was excellent, and some of his other films like Memento and Inception have gone on to be modern classics. Unfortunately, Nolan finally hit a stumbling block with his ninth film.
Interstellar wants to be a space epic in the vein of 2001: A Space Odyssey. It also wants to feature a labyrinthine mystery like Memento and be mindfucky like Inception. Sadly, though, it’s none of those things. It just gets bogged down under its own weight and Nolan’s ill-advised aspirations.
