Interstellar involves a topic that is rarely explored accurately in films. It goes into the effects of black holes and gravity, the most prominent of which is the relativity of time. It executes this to near perfection, only held back by the focus of the father/daughter relationship (i.e. it forces the passing of time to limit to the length of a human lifespan such that the father can still see his daughter), the time relativity could have been used to a better effect if it was allowed to dilate time further. Unfortunately, Interstellar suffers from a terribly dragged out and boring beginning, it takes 40 minutes before the characters even lift off from Earth. Once they get to the black hole and exoplanet, it gets to get thought-provoking, allowing viewers to contemplate the effects of gravity and space travel. While the film does break the immersion from time to time with a strong human emotional focus, it doesn't diminish the achievement the film succeeds in. The climax in particular provided an amazing closure and made the beginning of the film worthwhile. It also gives a sense of wonder for anyone who has a bit of knowledge into dimensions (i.e. the spatial and temporal dimensions). That said, the ending was ambiguous and glosses over how the characters survives but otherwise, a fantastic film that while it can be boring at times, provides enough tantalizing teases to leave you craving for more.
