There are two ways to go about creating a movie that’s so-bad-it’s-good (or “good-bad” as I’ll refer to them from here on). In its pure form, a filmmaker lacks the competence, awareness, and funds to create a good movie. A good-bad movie can also be created if the filmmaker knowingly sets out to create schlock but has the talent and ambition to surprise the audience with the outlandishness of the premise despite the limited resources. Big Ass Spider! attempts to be the latter, but director Mike Mendez lacks the requisite ability and drive to push his movie past the promise of its B-movie title. The result is the worst kind of good-bad movie where the filmmaker cynically creates a proposition where he thinks he can’t lose.
