Great movie, but what a stupid end

Rating: 5/10 (17 March 2015)

The movie is really great. Great suspension.
I didn't like the guy that tries to murder everyone, but thats OK.
But the best tip I have is the following: Please watch this movie until the guy goes into the black hole. Think he is dead and human kind did not survive. If you do that, this movie can be rated with a 10.
Really, what a stupid end. How can the makers spoil this great movie with this end.
I don't understand why this whole book case scenario is important. Has it to do with multiple dimension, did the makers wanted to show how this can be made or something. The guy just had to be stretched out and had to have seen himself falling apart in the black hole where time almosts stops. That would be far more realistic.
