Unmasked Part 25 (1989) 
British slasher satire which takes knowing pot-shots at US slashers (notably the Friday the 13th franchise), whilst at the same time telling its own tale of the deformed and mis-understood loner Jackson, who spends his life masked and killing folk in various gory ways until one day he meets the blind Shelley and things start to change. Jackson starts questioning his whole existence and re-evaluating his status in life and whether killing is really for him, as romance begins to blossom between the couple.
A clever, fun, and surprisingly touching film in places, which handles the diversity of its genres to great effect whilst expelling deadpan humour in droves. I regret not checking this one out sooner.
