A fantastic movie, riveting from start to finish; this film has a great story, is intensely realistic, and the acting is... hard to put one's finger on. George Clooney kills it as usual playing the confident, charismatic alpha male role and fills his role well. Sandra Bullock on the other hand, grated on my nerves throughout, though I'm unsure if I should blame her or blame the writer for the portrayal of the surviving female astronaut as a clueless, whining, and petulant child. The absolute inability of her character to deal with reality as it arrives wave after wave is hard to watch at points.

That being said, this is a family-friendly film that is terrifying solely through the realistic portrayal of the harrowing situations a modern astronaut could still reasonably face while in orbit.
