So basically you should forget everything established in the first movie and about the cannibalistic humanoid underground dwellers as this movie has absolutely nothing to do with that movie. That movie while not all that good did at least look like a major motion picture while this one has the looks and is a B movie that tries to be a comedy. Basically, this movie is more of a zombie feature than the creature feature the first movie was. I am betting they did this to save money on make-up and monster effects as these creatures only have dark circles around their eyes and some deformed teeth. They did not bother making this movie a true zombie movie as that would have had to perhaps have decaying effects and wounds. In the end this movie is more like the film "Night of the Creeps", but not as nearly as good as far as the effects and gore or the humor for that matter. In the end the movie is a sequel in name only. The only reason this movie is called CHUD II it seems is to have the little subtitle Bud the Chud for the cuteness factor and comedy factor which is basically none existent for my tastes. The plot just has Bud infecting others and the horde of zombie like creatures grows and grows. Nothing new or funny being brought to the table in this one, but I did rather like the infected poodle.
