I did not understand some. As a Sci-Fi fan, I looked forward to see this. The Earth in peril is not a new idea, and much of the film is derivative. 2001 and Contact come to mind. The acting is so-so. And the CGI is nothing special. It is also far too long, which I do not mind, if the film has the scope to need it. This one does not. Anne Hathaway: what is all the fuss about. Mathew is a fine actor, indeed one I did not like when first I saw him. The journey through the Wormhole was better done in Contact. And how come an ice cloud would not fall? The planets they reach are dull. Water without a sign of life. A frozen planet is not a place humans would like to settle. Then half way through I was completely baffled. (Spoiler alert). Why did Matt Damon's character rebel? Perhaps a revisit when on TV will clarify.
