Take a hot bath, eat some prunes and drink some strong coffee - anything to remove all trace of the travesty that was the 2009 movie from your mind + body.
Then immerse yourself in the complete run of the originals - upto and including FvJ.
Admittedly there are a couple of hmmms in there, but to skip any inbetweeners would (I think) mean missing out on the whole Jason experience. - avoid all spoilers though.
One thing I loved about the series was the gore never reach the "shield my eyes" level, yes it was graphic, but never prolonged and torturous like a Saw and its bone twistings or acid arm dissolvings. (yes, I'm a big wuss)
BTW if you try Wrong Turn 1 and think

, then methinks you'll be impressed with No2. Just give it ~7mins, or at least until the first kill. That was all it took for me to
know they were on to a winner. - I'll say no more.

But No3 - yuck.
