Liked it, reminded me vaguely of...
a movie I saw in the '70's as a little kid on the "Creature Features" TV showcase - The Flesh Eaters (1964)...I haven't seen that old movie since, just remember that it was cheap and campy, though scary enough for a little kid back then.
Levinson's movie is creepy, and not campy. I personally liked it better than Soderbergh's schematic, happy-ending-tagged Contagion...
