I like Poltergeist II better also, just by a little though. Mainly because Reverend Kane is so eerie.

Reverend Kane is awesome, too bad he didn't live up to his awesomeness in the 3rd one.

He was recasted in the third since Julian Beck sadly died during the production of the second one. You could tell the replacement just didn't have the same magic.

Part 4 is my favourite - not saying it's the best - just my favourite!

Amityville 2 is way better than 1, also agree with Phantasm 2.

Definitely Evil Dead 2. This sequel is so bad in terms of plot, acting and humour that it's actually good :). Sam Rami said one time that ED2 was the movie that he'd like to make from the beginning.

And of course there's the nostalgia factor - it was one of my first horrors.

The Grudge II
When a Stranger Calls Back

For my part I would say

Phantasm II
Return of the Living Dead 2 (funnier, IMO)
Dawn of the Dead and Day of the Dead
Friday The 13th Parts 2, 4, 5, 6, 7
A Nightmare On Elm Street Wes Craven's New Nightmare
Exorcist III
Puppet Master 2, 3 and 4
Evil Dead II and Army Of Darkness
Maniac Cop 2 and 3

These are subjective though. Ask me tomorrow and I may have changed my mind

Agree, ED2 was superior to ED. Of course ED2 is a remake, not a sequel. I don't think the plot, acting or humor of ED2 was worse than ED.

For whatever reason, liking ED tends to depend on if you saw ED first, or ED2 first. Could be many reasons, but I'd have to point to nostalgia as a reason to like ED better or equally well as ED2.

Personally, I just think Evil Dead is a better film. I prefer it because of its darker, more serious tone. Although, I did see that film long before its sequel. (On home video, of course)

I agree as well. I love the feel of the original. Evil Dead II had a bigger budget and more comedic elements and things that generally make for a better more re-watchable horror film, but I still think the overall darker tone and feel of the original wins for me.
