I just loved watching it though and having fun with it's total badness of a film. I saw this film through the helpful sarcasm of Mystery Science Theater 3000 and I have the DVD. If you flip the to the other side of the DVD, they show the actual movie, so I gave it a chance. Seriously, folks this is grilled cheese.
The acting, special effects, and plot in general is very cheesy and unrealistic. "Doesn't she need lungs" said Crow noticing how the head can still talk while it doesn't have a body, and Tom Servo just wistfully remarks "No, she's got neck juice!". The ending is just classic and no one can touch this soundtrack with K-Porn! I loved the "cat fight" between the two strippers. That "Meow" after the fight or scene, whatever, was classic. So, in some ways this was a fun movie. I think for horror fans, you'll probably enjoy it. For a good time, watch the MSTK3 version, you'll get a great laugh.
