I quite like the ridiculousmess of Jason X to be honest. It's just such a silly idea you can't help but go along with it.
I Sky+ed Freddy Vs Jason last night as I haven't seen it in years. Will be interesting to see what I make of if this time round. I agree with Nos about Friday 13th - the first three make a really solid slasher trilogy. All goes a bit pear-shaped after that.
