Instruct: Classify Amazon reviews into positive or negative sentiment
Query: I liked it...

Definitely should be viewed as a precursor to Alien (I don't know why some people debate that?).It wasn't a perfect movie... and it did seem a bit different than the previews made it out to be (but that always happens, doesn't it?), but it was a good movie. Entertaining and worth watching.Amazon's instant video version of the film shows a couple clips right before the movie, saying "stay tuned after the credits to see this alternate ending and deleted scenes". The trouble is, those clips are sort of spoilers. It shouldn't show them then.
