Once more I've written a review on a really trashy bad movie -
Cool World. I wouldn't have thought it'd fit the 'so bad it's good' bill, but it really does have a lot of these classic 'bad movie' moments. This movie kinda has a bit of a genuine cult following on the internet, so I went very in-depth in analysing how bad of a movie it really is to show these people how silly they are.
