Hmm... I'd say Godzilla 2014 is the best of the American Godzilla movies (with only 2 to choose from).

On other movies, I'd make Alien still the best of the Alien series (though Aliens contends with it), Predator 1 the best of where the predators appear, and Transformers 1 for all of this series. Usually, for me, the original would be the best. Some sequels seem forced.

In Hammer Films' series... make it The Vampire Lovers for me. hehe

Transformers isn't Horror, though.

I don't think I mentioned them before, but I remembered the My Super Psycho 16 films. Never seen them but they seem pretty decently-received.

I saw 1 & 2, Jig, and all things considered, I was quite taken with them.

I've heard a lot of good things about them. I'll seek them out someday, maybe my library has them or can reserve them for rent.

Looking through the thread again I don't believe I mentioned the Cold Prey films. Never seen them but they've been pretty well-received from what I've read on them.

I don't believe I mentioned the Children Of The Corn series before. I've seen the first two and parts of the third and fourth. I'm not sure how many films in total there are in the set.

None of them were as good as Fulci's Zombie/Zombie 2/Zombie Flesh Eaters. Zombie 3 was ok but suffered as Fulci wasn't involved much could of been much better but still ok to watch. Zombie 4:After Life was terrible but Zombie 5: Killing Birds was really fun I enjoyed it a lot. I'd definitely say Killing Birds is the one I would recommend most.

Not seen any of them I'll have to look out for them

I enjoyed all three I think I enjoyed the 2nd most but I watched them close together and the lines blur a bit for me. I'd go with the 2nd maybe then the 1st as my faves. I'll re watch them at some point.

Excluding the remake and it's seuel there were 7. The first is my fave. I've seen up to part 6 (or 666:Isaac's return) but never part 7: Revelation. I'd like to see that someday so maybe I'll revisit these as besides the first film I've only watched the others once but the quality did dive after the third as far as I remember. But I think they are worth another chance.
