I thought the movie was great. Tense and the pacing was well done. Not too long and didn't drag. The astronauts are dumb and it's easy to say don't go in there when you are watching. I like Jake Gyllenhaal I think he's a great actor and [spoiler] too bad Ryan Renyolds died so early in the movie but I kinda was expecting it based on the posters him being the third name. The twist at the end i saw coming as soon as they got in the life boats but it still was done well with the fishermen finding him. [/spoiler]

Wow, this movie had so much potential but in the end it fell well short. The huge plot hole for me was: [spoiler]how did the creature get back inside by going through a thruster bell/engine? The ISS uses a hydrazine compound as a propellant and it is extremely toxic. This would dictate that there is no way that the thruster bell/engine would be connected in any way to ISS internal atmosphere. If it was, the atmosphere would leak into space![/spoiler] There were other things wrong as well but this was the biggee for me.

You look for serious sci-fi ? Move along. I was out of this movie about 45 min in. [spoiler] Should have been out earlier about around when they caught a capsule moving thousands of mph with a grappling arm without breaking anything. Yep, that is the level of science here. More ? - Rampaging with some kind of a flamethrower in a laboratory without damaging anything. - how much coolant can there be in a spacesuit ? - can an organism lay dormant for what might possibly be millions of years and then develop into a complex lifeform ? Of that I´m not certain. Then there is the typical illogical behavior of the characters that is nessessary to propel the plot. And the CGI for that alien is bad, you always recognize it as beeing CGI. Which is weird because the rest looks pretty good. And the end ? As if nobody saw that coming. They need to prepare a sequel [/spoiler]
