Featured review
Surprisingly Good!
This is one of those rare slasher films where you actually want nearly everyone to survive. I found myself halfway through this film thinking, I wish this was a comedy or a drama so I wouldn't have to watch these people die.
The slasher elements are actually the weakest part of the story in my opinion.
The lead final girl was a bizarre choice for the role. Something about those eyes. Very good actress though. The supporting cast is excellent. I thought I might finally see Tom Hanks get killed. Alas it wasn't to be.
If you've watched Halloween 700 times and have worn out The Burning, My Bloody Valentine and The Prowler, give this Suckerbugger a chance. You Shant regret it. Shant.
