Unless you have the scientific understanding of a teenager the movie isn’t that hard to understand. I know there are probably a lot of astrophysicists and people that study general relativity that can point out a lot of technical flaws, but in my opinion I thought the movie was an amazing adventure that served as a bridge between science and fiction, theory and imagination. This is the only review I’ve ever given about a movie and will probably be the last. Great movie, and if you’re into astronomy you need to see it.
