I hope the makers of Alien Raiders will forgive me for noting that it's not as good as Alien, The Thing or your favorite adaptation of Jack Finney's The Body Snatchers...
Alright, smart ass! If your favorite is The goddamn Invasion, then, yes, it is better. There. Do you feel better now?
It is, however, much better than the kind of Sci-Fi Channel original movies that the distributor seems comfortable making it look like. It's actually a rather smart and taut thriller about a group who locks up a Supermarket, but turns out to have more complicated motivations. I'm not going to give away too much, because it is a nicely twisting and turning, if not entirely un-predictable plot.
(A brief word on surprise and predictability, since they seem important to other people. Surprise is overrated. The kinds of movies it's expected from are the kind that we describe as roller coaster rides. Unless you're blind, roller coaster rides are not actually surprising. You can see every twist, turn, climb and fall before you even get on and again long before they occur. Surprise is highly overrated as an element to a thrill. Which isn't to say I'm a fan of the wholly predictable either... it's, well, never mind this is a whole essay of its own...)
Kept within a single location, the Supermarket, it only rarely threatens to become stagey. The story moves along at a good clip and the suspense is kept nicely. Hopefully a few more people will comment on it, because it deserves to be called out as a solid sci-fi thriller.
