Ghastly.
The first two thirds of Sunshine were fair. Nothing great, but fair. There were immediate problems from the very beginning (such as using a calm voice when it should be awed, and the exact opposite as regards the music), but I liked the fact that none of the crew members were either particularly heroic or evil, but just ordinary people. But I certainly sat there wondering where the hell this story was going. Then came the last part, and, as is the case with so many bad movies, it went straight to hell in a hand-basket. Throughout the movie the logic between events were unclear. Where were we? How did we get from one situation to the next? How did this or that bit work? There was an abject lack of explanations for a host of things, from what exactly was wrong with the sun, and to just what it was that caused the Earthroom fire.
But it can be argued that these elements are not important, because the producers were trying for an art movie. So the substance is all in the themes: World is doomed; scientists are trying to save it; insane religious fanaticism is sabotaging science. Also the scene where they vote on whether to kill Trey: Cassie is the conscience; the emotional and irrational heart among all the rational analyses. Sure. Nice themes. But utilized inside the confines of an utterly incompetently structured narrative.
Nothing made sense. For instance, I could write several pages on the zany way this movie treated gravity. And how it tried to get by on clichés. And was unsuccessful in building suspense due to sloppy writing, directing, editing and sound effects. The creators of this movie know very little about science fiction, and they should stick to what they do marginally well: horror.
Sunshine was a failure, and its IMDb rating (currently a staggering 7.8!!) will plummet when more people (such as actual SF fans, and people who're not friends of the the director) see it. Halfway through it I thought it might merit a 5 rating, but the ending was so ludicrous, unbelievable and stupidly put together that I can only end up awarding the movie a 2 out of 10. I now believe this movie has the worst ending of any sci-fi movie I have ever seen. Event Horizon, move over!
Sheeze.
