This is by far the most disappointing movie I saw in many years. It is even more disappointing, because I had rather high expectations after seeing the 9.2 rate at IMDb. 9.2!!! Really? The movie is way too long, it is very slow and mostly rather boring. The plot is stupid to say the least with a lot of scientifically sounding lines which make no sense. And the visual effects are ... not really impressive.

Why on Earth had Matt Damon taken that stupid and nonsensical role?

And this comes from the director who made Inception and Memento ... what a waist of resources.

Save your time and money - watch something else.
