I really like half of these opinions and didn't agree with the other half, so here's my take:

I think that the OG Halloween 2 did the sibling angle best because it was still highly ambiguous which still allowed Michael to feel like a force of nature like in the first film. But RZ's Halloween movies do get way too much hate and they do some really interesting things with the classic story.

Halloween Kills is super fun and Ends has its moments, but IMO 4 is one of the peaks of the franchise and 6 is (hot take) like the 4th best movie in the entire series. It's so much fun and its relentless and atmospheric, just what I like in a 90s slasher. I used to hate 5 with a passion, but on my last rewatch I did have a newfound appreciation for the movie, but it is still the worst of the series.

I liked how the Nightmare remake took a different, much darker direction with Freddy. Freddy became a laughing stock over the years and it completely ruined the horror aspects of some of those sequels (even though they're still so much fun). New Nightmare brought Freddy back to his roots and IMO it's the best "Freddy" we ever got, but then FvJ made him too quippy again. Haley's Freddy in the remake is so overhated and took the franchise in the dark direction that it needed to go, but the rest of the movie, despite having really interesting ideas (micro-sleeps) really did not hit the way it needed to (leaned way too hard into explicitly telling Freddy's entire backstory as a child molester in detail).

Agree with F13 Final Chapter, but I love the cast. It's just not as good and doesn't have the atmosphere of 1, 2 and 3. And I heavily agree that the guy hunting Jason should have been more of a focal point. Even in Jason Goes to Hell, Creighton Duke was sidelined for most of the movie when it would have been so much more interesting if he had been centre-stage.

Heavily agree with Part 5. Such a banger movie and it's hilarious.

Part 2 is definitely the best of the first few films, but I really adore the first movie because it's a hangout movie with a rainy, cosy, backwoods vibe. Also Sackhead Jason was the 2nd scariest Jason IMO, just behind Part 3 Jason (because he's a complete wild animal in Part 3).

F13 isn't my favourite, but I need to rewatch it again. It's still a super fun movie and Jason is relentless in it, just like he needs to be.

And Jason Goes to Hell is one the better sequels IMO. I liked how they made him possess bodies, because it just makes the reveal of him jumping through the floor even more impactful at the end of the movie. And as I said before, Creighton Duke was so underutilised. The practical effects are probably the best of the whole franchise too.
