I've been browsing through the Wikipedia's list of slasher movies so filling the gaps:
100 ghost street: The Return of Richard Speck - a la paranormal activity. the ghost of serial killer who was molested by his father returns and kills a group of teenagers and the film is made only from found footage. waste of time.
And while going through the list, I'd say these were good slasher movies too: Bloody Birthday, Eyes of a Stranger, of course Halloween, High Tension (!!!), Hell Night, The Mutilator, Schizoid, Trick or Treats, Unhinged, Wolf Creek.
Of course Texas Vibrator Massacre should be good, but didn't see that. Also the recent Shrooms was said to be one of the best slashers of the history etc., but I don't quite know why it should be one of the best.. It's decent.
Cold prey is quite new Norwergian slasher. A group of young people are going for skiing and one of them breaks the leg so they find shelter in some old hotel and the killing starts. edge of the axe was made for tv I think so it's quite different, but overall pretty good.
and yes, the burning and MBV are great. though I liked the original more and the remake of MBV was a little disappointing.
