This gets a couple stars for at least trying to be an unusual and ambitious sci-fi film. Around 20 various minutes out of the film are pretty great, but the other 2 hours are like a black hole that sucks you towards it's (rather fluffy) mass of awful. The script is full of clutter and handy gotchas, and McConaughey is out to freaking lunch. I should have learned my lesson after the inevitable misfortune of seeing Inception, which was nevertheless a somehow more sensible and interesting film than Interstellar. Nolan tries to get his Kubrick on here, but the results are a film not even half as good as, say, Event Horizon - a nearly 20-year old flick that probably used a tenth of the budget that this one did.

TL,DR: rent Moon or even Pandorum before this.
