It doesn't happen often but I gotta disagree with the HDTGM gang on this one. All I remember of it from when I saw it as a kid was someone making a quip about a vent pipe (trust me it was hilarious) and Aykroyd's penis-nose. Had to rewatch it just now and, unlike the majority of HDTGM picks I've forced myself to watch, I could actually sit through the whole movie with this one.
If the movie has a problem it's a lack of any real solid jokes, but it more than makes up for it by being as interesting and left-field as it is. I mean those final two plot-twists? Holy shit.
So yeah. God help me but I like this awful piece of trash.
