If you saw "sunshine" and thought "wow, good thing they had scientist advisers, this stuff is so plausible", you will like "interstellar".

If you saw "armaggeddon" and thought "what an awesome movie, i just wished they would have dragged the scene where he says goodbye to his daughter out even more", you will like "interstellar".

If you saw "inception" and thought "this movie would be so much better in SPACE!", you will like "interstellar".

And if you liked "2001" or any other intelligent/geeky sci-fi movie, you will hate "interstellar".

Like some of Nolan's earlier works, it's long for the sake of length only. Its plot is up there with "armaggeddon" in pure stupidity and forced US-cowboy-patriot-macho-ism, its special effects are underwhelming, its plot twists are obvious, its setting makes no sense, its characters are flat and forgettable, and its constant citations of "2001" just serve to make you remember how much better Kubrick did all of this with a tiny fraction of the money almost 50 years back.

Disappointing.
