If you want to watch good fiction, this movie is awesome.

But if you try to make any sense out of this movie, you will find many serious flaws in the concepts of this movie.

Nolan tends to lose focus from the story line as usual and ends up with same concept in every movie. The most ridiculous scene was when Cooper enters into the gravitational field of black hole and finds out that "they"(future human-beings) have created 3-D projections of his daughters room in 5-D reality..

This movie has made serious fun of Physics, Gravity and Black holes.

Its just a fiction movie, highly overrated on IMDb.
