Jigsaw is one of those no-budget horror films that has plot holes you could sail a cross-channel ferry through.
Here we have a mannequin that gets burned then comes to life and kills everybody. How and why does it come to life? We have no explanation.
Acting is woeful as is every other aspect of the movie. Jigsaw is as formulaic as slashers get with one survivor at the end but a lack of closure that allows room for an unlikely sequel.
I think I’ll go as far as saying it’s worse than Manos, with no redeeming features at all.
