Before I get blasted, I want to acknowledge that I am familiar with Full Moon films and have seen quite a few over the years (the 'Trancers' series is among my favorites), but 'The Gingerdead Man' was an unfortunate mess. There are pros and cons, though... and believe it or not, the killer cookie (looking very much like it's made of rubber) is the best part.
I've become a fan of Gary Busey in his "is he insane?" recent years, so his presence either in live form or vocally as a cookie is really amusing. The other actors aren't as bad as one might expect, either. But everything else in the film drags and drags and draaaaaaags, not to mention the production budget appears to be under $100 (check out the bakery sign that looks like it was painted for a junior high pep rally). I know these flicks are self-financed, and that's a great thing, but there wasn't much to work with.
The movie clocks in at around 60 minutes, so for there to be so many slow spots (i.e., scenes sans cookie) it was difficult to watch. Will this be a cult classic? Yeah, probably, just given the featured actor and the premise. But it's just not very good, even by Full Moon's standards.
