I saw this on Wednesday night and I thought it was pretty awful. 2 hours and 49 minutes worth of pure torture. A lot of people loved it, though, as it has a 9 stars out of 10 rating on imdb.com.
Here is a sampling of the imdb.com "hated it" review titles:
Giglia in Space on Drugs for Stupid People
Bloody Awful... Space has never been so dull...
watch if your local pharmacy has run out of nytol.
More plot holes than swiss cheese & a total waste of the 70mm film it was shot on.
Worst sf film in 20 years
I know i am currently in the minority but it was bad.
Not quite the Worst Movie of All Time
Don't waste three hours on this - It's totally boring!
Pure unadulterated dog squeeze. Torture!!
