From the top of my head I'd say some of the best slashers I've seen were: Cold Prey, edge of the Axe., April Fools (first one), Anthropophagous 2000 (ignore this if you hate shitty gore effects), Friday the 13th (1,2,4 parts), black christmas, don't go in the woods, eyes of a stranger, the prowler, maniac cop, the prey, silent night, deadly night. also what were those two where the killings were done in the theater on stage and another one where the killer was dressed as uncle sam. Don't remember the titles, but they were enjoyable.
