The first 3rd has the family being slaughtered by punks looking to score big money by robbing the family.
The middle act has a twisted and ugly man chasing down the punks and killing them, and the aftermath with the survivors and the police.
The conclusion sees all of this as a bad movie in a theatre and showing us what the 'real' monsters are.
Not one of these acts would have made its own good movie, the summation was even worse.
Wacky shit, worth a rental.
"Grotesque" is a typical home invasion horror flick with a young woman (Linda Blair) and her best friend (Donna Wilkes)traveling up the snow packed Rocky Mountains to spend time with her parents. When some sadistic splatter punks invade their home, killing many of the family members in order to find money, Blair's grotesque and misshapen step-brother decides to get vengeance.
What gets me about this film is it has so much fucking potential. Blair and Wilkes ("Angel") are exploitation goddesses and they are sorely underused. The plot of the grotesque brother is not given much back story and the film runs completely dry at the hour mark.
The punks themselves are so over the top and sadistic that one can't help but laugh. The best way I can describe them is the 'splatter punks' from the beginning of "RoboCop 3" with their wild spiked hair and pasty skin. They are so fucking nasty that you truly root for them to die in the absolute worst ways possible... the aspect the film sorely misses its mark on.
Other then Blair, Wilkes and our lead punks, the acting itself is quite atrocious. The worst is the two bumbling cops trying to solve the case. What did they do, cast two local yokel cops? The make-up effects also leave a lot to be desired, which is ironic as Blair's father in the film is a Hollywood horror movie make-up artist.
However these are just minor quibbles compared to the shit of all shit endings. You think the dream ending to Umberto Lenzi's "Nightmare City" was a cheap cop out... you ain't seen nothing yet! I had to restrain myself from throwing my Iron Maiden 'Eddie' bobble-head doll sitting on my coffee table through the television screen. I shit you not this is one of the worst fucking endings I have ever seen!
I wanted to like "Grotesque".... I really really did. The snowy mountain setting, the exploitation cast and the idea of a misshapen monster killing punks perks my interest but this was a poorly executed excuse of a horror film with the end-all worst wrap-up ever. What exactly Blair saw in the script to also serve as producer is beyond me.
