Great effort, worth seeing, but story quite flawed

Rating: 8/10 (11 July 2009)

9 out of 10 for being well-done and an attempt at serious science fiction. But as a film, at best 8 out 10 (maybe 7.5).
Nicely done, nicely played, very nicely acted. But the story has holes bigger than the craters on the moon. To name them is to give out spoilers, and the movie is so nicely done and so captivating that you don't necessarily recognize the story line flaws until late in the movie, or even after the movie has ended; you know, one of those "hey, how could that have happened?" or "wait a minute, why did they do that?" moments. It's too bad, as the story could have been without many of its essential flaws and inconsistencies. The external shots are nice, but in many cases look like models rather than the "real thing."
Still, a valiant effort, and worth seeing.
