What do you think about the movie "Pandorum"? (Spoiler alert)

I just saw the movie “Pandorum” and I was pleasantly surprised. When I told my mother that I was going to see it, she said it looked like Alien, only stupid, which pretty much summed up my ideas about it. However, when I saw it, I soon realized that it was actually a pretty well thought out film. I’ll admit that the whole “pandorum” thing confused me for a little while until the end when it was really meant to be an amalgam of different symptoms plus I wanted to say “amalgam” of insanity.

I do think the movie would have been much worse if the ending had been different. what does the collective think?
