Just saw this on SciFi channel. Big disappointment after reading some of the promising reviews here. I always give scifi movies a bit of extra leeway as I like the genre, but Alien Siege is just plain poor.
I agree on two points others have made. Good story line which deserves to be made into a decent movie some day, and good visual effects.
That's about it though for the good bits. The direction was pedestrian, no build-up of tension or drama. Terrible screenplay, you'll find better dialog in comic books, and the characters never engaged me in caring about their fate. The acting was generally well below B standard, although in fairness the cast had very little to work with.
I rate this 2/10 for the story and visuals. I kept waiting for it to improve, but it didn't happen. Oh well, sometimes the bear gets you...
