Best Film In a Horror Series

Had this up in the Horror sub-forum here and figured I'd bring it here as well to FG given it's more active here. Of the following Horror series with at least three or more movies, which is your single favorite entry in each? Just cut and paste the list and replace with your choices and feel free to add any other series I forgot.

My choices:

Friday The 13th - The Final Chapter
Halloween - 1978 Original
A Nightmare On Elm Street - New Nightmare
Saw - Saw II
Scream - Original
Evil Dead - Evil Dead II
Phantasm - Phantasm II
Alien - Aliens
Predator - Predator 2
Hellraiser - Original
Child's Play - Original
The Texas Chainsaw Massacre - 2003 Remake
Final Destination - Original
Insidious - Chapter 3
The Conjuring - The Conjuring 2
The Purge - Anarchy
Paranormal Activity - Original

And some additionals:

Hannibal Lecter - The Silence Of The Lambs
Puppet Master - Puppet Master 4
Maniac Cop - Maniac Cop 2
Romero's Living Dead - Day Of The Dead (1985)
Return Of The Living Dead - Part II
Poltergeist - Poltergeist II
Jaws - Original
Cube - Original
Tremors - Original
Leprechaun - Original
Blade - Blade II
Wishmaster - Original
Warlock - Undecided between either of the first two
Amityville - Only seen the original, remake and It's About Time
Resident Evil - Seen the first two, need to see the rest to make fair judgment


Also should note the two Annabelle films are included with the two Conjuring films, so The Conjuring counts as a 3+ movie series.

I'm sure some of my choices are sure to be controversial like Predator 2 and Poltergeist II (both are bold, I know). Not to say I disliked the originals at all, just enjoyed the subsequent movie a little more. I bet me liking the TCM remake is bound to raise more than a few eyebrows.
