Sunshine is near-classic modern science fiction, hobbled only by a chaotic final reel and some casting missteps in the white-male department.

Another thinking-person's thriller from director Danny Boyle and writer Alex Garland, also co-pilots on "28 Days Later."

A first-rate, seemingly sweat-free entertainer, Mr. Boyle always sells the goods smoothly, along with the chills, the laughs and, somewhat less often, the tears. He’s wickedly good at making you jump and squirm in your seat, which he does often in Sunshine, but he tends to avoid tapping into deep wells of emotion.

Hard-core science fiction fans will likely greet Sunshine with a smile. Others may find this to be an odd motion picture, but there's enough going on that even those who are expecting something flashier should still be engaged.

Science-fiction fans will like it, and also brainiacs, and those who sometimes look at the sky and think, man, there's a lot going on up there, and we can't even define precisely what a soliton is.
