Personally, I do like 2h-and-longer movies, but only if they can attract my attention in full durance. This is very very good movie, but I wouldn't say a masterpiece. Why? I expected more convincing turns and twists. Example; When the crew finds out that they were fooled by dr.Brand, it is hardly well explained what kind of purpose leis in their expedition. Dr Brand says there is no hope to find the ˝salvation planet˝ because his equation is insufficient, yet they still have to continue their research, as dr. Mann says: they are the future, not the Earth inhabitants. What's that mean? They will die searching? What's the difference then between them and those left behind??

Nolan is one of my favorites, but still something's missing here.
