How bad is it? It's a trainwreck.
Should you see it? It's worth a look.
This film has a cast of three people, one of whom is among the worst actors ever put on screen (the others aren't great, but look good in comparison) and it's his performance that gives this film cult status among bad movie buffs. Two people try to steal money from a rich man, who has apparently turned his enormous underground bunker into a series of games to solve and traps to avoid. None of it works. Episodic in nature, with minimal sets, this relies on character to succeed and we're stuck with Lazar Rockwood, perhaps the worst actor to come from Canada (move over, Shatner!), whose lines are mumbled and who causes us to want him to fail. Spoiler: he fails; and the explosion is off-screen, so there's truly nothing to see.
