I can't name any horror movie ever, which ever enjoyed any sequel which was worth a damn.
Sequels in general are worse than horsefly excrement. Nothing is lower than fly s**t.
By and large, I refuse to bother wit' 'em.
Yes of course, I've seen a few –by accident, against the advice of my better angels – but at the end of the day, I can use no more than the fingers of just this one hand to list the ones which were palatable.
If I recall, there's only this meager passel of titles which make the grade:
French Connection II
Rocky II
Star Trek II
If you name almost any major franchise within range of my earshot you'll find a black mark against it in my book. Star Wars, Raiders, nothing but boojwaah, to my way of thinking.

Halloween
The original Halloween is better than any Friday the 13th film but, overall, the Friday sequels are more entertaining than the Halloween sequels (the excellent Halloween III: Season of the Witch being the one exception). We got to see the evolution of Jason in the first four Friday films, whereas Michael Myers never really changed. Most of the Halloween sequels are interchangeable and forgettable; the 2018 reboot was pretty good though and better than the previous sequels. I never liked the NOES sequels but I haven't seen all of them.

Saw.
What happened to the American Dream? It came true! You're lookin' at it…

Halloween. Season of the Witch was an interesting departure, and I wish they made it an anthology series instead of all about Michael. I never found Halloween that interesting. I appreciate it for helping to establish a subgenre, but it's my least favorite of the main franchise. I also don't like how he's not supernatural, but behaves supernaturally. I know in later sequels, they made him more supernatural, but he wasn't supposed to be.
The Nightmare series is my favorite. There are a lot of bad sequels, but they're bad in a fun, visually appealing way… and 3 and New Nightmare are arguably better than the first.
I feel like the Friday sequels are mostly better than the first one, which is kind of boring. Not my favorite franchise, but I like it, especially when it's dumb.
Not mentioned here, but while Chucky isn't as much a fav as Freddy, I find all those movies are consistently good to okay. 2nd is my fav.

Best of the bunch…still utter horse ****

Ahem. You may have heard of a little film called Prometheus.
I accept your apology.
What happened to the American Dream? It came true! You're lookin' at it…

Alien! Sure…Aliens was great…but absolute dogshit thereafter

Well, it's not like
Friday the 13th
was ever even remotely good to begin with.

Halloween. The plot got more and more stupid.

I do like NoES, but each sequel got progressively worse.

A compelling argument.

properly answering your query with interpretive dance -

5th one does something new. I also like the 6th one's self awareness, and they finally get campers at the camp.

i love it too, in fact, i like part 2 more than the first one and Jason Lives is great as well, but you're right lol

Friday the 13th is basically the same movie over and over with the exception of different kills. I still love the franchise though lol

overall i'd say Friday the 13th bc
Nightmare on Elm Street 3: Dream Warriors
and
Halloween III: Season of the Witch
are masterpieces in their own right.
