great movie with 3 floats for me..

Rating: 9/10 (6 June 2012)

I loved this movie and enjoyed every single moment watching it.
But in the it left me with three questions:
1.when they arrived the planet, how da hack they directly went to the exact point of the "ship building" (since they've found it accidentally)
2. after the "self-surgery", Dr. shaw was pretty much in pain but suddenly she became a Rambo! (was it adrenalin, or what?!)
3. how many kinds/forms of aliens did they have? there were the octopus- like, snake-like, a gigantic one.. they should have related all these kinds at some point.
Anyways these are all little mistakes, this movie should be seen in theaters, definitely worths sparing time and money after all those Hollywood crab!
