It is altogether a solid sci-fi film, entertaining, if more action than horror. The xenomorph models are well done and the struggle of the crew really has you on the edge of your seat. If there were any complaints it would be that I'd have liked to see more character from the crew. My personal favourite crew member was the obligatory assh*le, just because he had personality beyond his party's purpose. Also, somewhat annoyed that the two white male actors were both made to be the villains, in typical modern media fashion, it's predictable at this point and therefore boring.
Altogether I think it's a brilliant film and definitely one worth watching purely on its merit as a sci-fi spectacle.
