I am just going to assume you have seen the first Friday 13th movie. I mean if you haven't ... why would you watch the sequel! It clearly states so in the title, that this is not the first one. Which makes it even crazier that this rehashes the last minutes of the first film. While Cunningham didn't get how or why they would bring back Jason Vorhees (he was dead, wasn't he?), Steve Miner took over ... and quite the job he had to undertake. Make the same movie but a bit different.
So right from the start we get rid of what remained from the first movie (excluding Jason that is). And then we get more teenagers for him to be mad at. Why you ask? Does it really matter? Let's say because they can live a life he never could and he hates them for it. That should be good enough. We also get a final girl that is quite clever. Even if not as asexual as some might remember her. She's quite flirty isn't she? Rhetorical question that was.
This sequel does not just see a different Jason actor ... it sees many of them. Apparently a lot of crew members literally stepped into his shoes. Though Steve Dash is the one who seems to take most credit for it. Some may question that, with other stunt man trying to make their case, but it seems he did the heavy lifting (or glass related stunt breakthrough) ... no pun intended.
Since the first Friday movie was so popular but also had many people who were shocked at the gore it had (again quite tame from todays standards), this had quite the issues. Especially because it tried to outdo the first one. So quite a few things landed on the cutting room floor. While this has more blood then, it seems to have less nudity. Though that does not matter that much I think - it's more about the killings isn't it? I think most would agree.
While this also contains Jason as character and killer, sort of the first time, it is not the Jason most might know, especially thinking of the later movies here ...
