The acting makes me sick...
I own this on DVD just so I have the complete series, and I enjoy watching all the others, even #5-but this one just makes me want to gag. I'm all for horror/comedies, in fact they're my favorite kind of horror movies, and sometimes, the cheesier the effects = the better, but when the acting is so bad like it is in this one, it just takes me right out of the fun.
Granted, it probably wasn't ALL the actor's faults, it was the terrible script as well. Also, I will admit that the acting in the rest of the NOES franchise was nowhere near award-winning...but Lisa Zane has to be the most inexpressive, blank-looking actress I've ever seen.
