Well, my orang-u-tan wrestler, I actually was very excited to see this for a few reasons:
a) Alex Garland wrote the script, and he did a great job with 28 Days Later.
b) Danny Boyle directing? Good work from him in the past.
c) I
lurrrve metaphysical sci-fi. eg. 2001; Solaris and this promised to be in that tradition.
BUT, when I read an interview with Boyle shortly before release, he was saying how much he doesn't like S/F, and that really worried me.
And so, the movie itself is not what you would be looking for monkey magic!!!
barely any action at all. Very slow, little plot.
The film is not really about re-igniting the sun. It's about what happens to men and women trapped in space with a huge responsibility and how that affects them.
If you're looking for a roller coaster of CGI and guns blazing, look elsewhere my simian overlord!!
