Originally conceived as a Return of the Living Dead sequel and later inexplicably re-titled (despite the highly questionable marketing value of a C.H.U.D. franchise) this clunky attempt at a horror satire involves a pair of teenage do-nothings who abscond from a military base with a corpse who turns out to be a zombie, the by-product of a backfired military experiment. Despite the C.H.U.D. (Cannibalistic Humanoid Underground Dweller) references, Bud (Gerrit Graham) is really a zombie of the George Romero variety, chomping down on human flesh and spreading the virulent zombie plague to those unfortunate enough to be onscreen long enough. Eye-rolling Graham is fun to watch, as always, and Robert Vaughn puts in a goofy performance as a rabidly gung-ho general, but they provide scarce gems of humor in a morass of reconstituted horror plot elements and lame jokes. The end product is more C.R.U.D. than C.H.U.D.
