Bought the 3D Blu-ray and watched it at home. Many scientific and technical flaws, lack of character development, and unfunny jokes overshadowed the special effects.

I was also very disappointed in a 91 minute running time.

I just couldn't accept George Clooney as an astronaut. Sandra Bullock was believable and did a great job with what she was given to work with. More background info on her character's personal life would have helped this viewer in understanding her mindset.

Better "space" movies are "2001: A Space Odyssey" (1968), "Sunshine" (2007), and "Silent Running" (1972).
