1001 Misspent Hours calls the movie "by turns boring and charmingly dumb". I missed the charming part. The Projection Booth begins its review with this:
Oasis of the Zombies deserves some sort of eternal recognition in the annals of cinema if only for it's brilliant alternate title, Blood Sucking Nazi Zombies (take that, Snakes on a Plane!). The film itself, however, largely fails to live up to such kitschy promise, and for the most part is a fairly typical entry in the legions of cobbled-together B-movie horror films.
