From my review in the August 28th issue of The American Conservative:
"Sunshine" is a medium budget ($40 million) science fiction thriller with art house pretensions about eight astronauts on a last-chance-for-mankind mission to reignite the dying Sun with a "stellar bomb" the size of
Granted, the physics of the premise are unworkable -- for one thing, it takes a half million years for light to jostle its way out from the dense solar core to the surface, so by the time we noticed anything was wrong with the Sun, it would be too late -- but, some of the film's conceptions of how much the freezing folks back on Earth could do if they had to are thrillingly old-fashioned. For instance, this bomb is humanity's final hope because "all the fissile material on Earth has been mined" to make it.
On the other hand, by 2057 NASA appears to have delegated personnel selection to a TV network. The crewmembers of Icarus II look great but display all the competence, cohesiveness, and cool-headedness of a losing tribe on Survivor. With the oxygen running out, they sit and debate whether it's morally justified to kill one person to save the entire species (uh, yup). "Sunshine" isn't quite as inane as last year's apocalyptic "Children of Men," which kept getting distracted from its plot about saving humanity from extinction to protest the plight of illegal immigrants, but it's close.
