Blockbuster rated this 3.5 stars out of 5
Had watched it for this reason back in '97 or '98. The reviewer said that Proteus is "The Usual Suspects meets Alien and The Thing"... LOL. Incidentally the guys at DreadCentral feel the same way about the Usual Suspects' influence.
I liked it more than Deepstar Six, less than Leviathan, and a hell of a lot less than The Thing. Was 17 years old though, so I might think it's a pile of crap if I had to rewatch it now.
