It's just what you'd expect it to be
It was just like watching a goofy version of The Collector and after reading the plot outline that is precisely what I had expected.
It was quite low budget, but they did well with it, and that is something I always give extra kudos towards which persuaded me to give it a 6/10 instead of a 5/10
Watching the film I couldn't help but wonder why exactly it was named Crush the Skull and when the scene finally came to explicate that issue, it was indeed pretty f'kin humorous.
