I had to sit through Pot Zombies yesterday and boy was it atrocious. I mean, for Troma, that's kinda what you expect, but you don't get that same B-movie charm you get from other Troma movies like The Toxic Avenger and Class of Nuke 'Em High. The makers of this movie knew they were making crap, but they direct is as if they tried to make us laugh at it's poor quality. With other Troma movies like (again) Toxic Avenger, Nuke 'Em High, and Blood Hook, they also knew they were making Troma schlock, but they kind of let the movie direct itself, go with the flow and don't put such a comedic emphasis on its poor quality.
This movie treats it's audience like imbeciles and tells us what we're supposed to laugh at (as if it were not already shoved in our faces). It's a lot like those (horrid excuses for) parody movies made by Aaron Seltzer and Jason Friedberg. They really push that comedy in your face to the point where you literally yell "Okay! We get it already!". If you want to make a decent B movie, watch Killer Klowns from Outer Space, Attack of the Killer Tomatoes, Mystery Science Theater 3000, or anything made by Ed Wood.
