..Well, it is not my FAVORITE Horror-Sequel but "The Human centipedes, centipede II (Full Sequence)" is somewhat better than the first (even though I kinda miss Dr. Heiter).
HC aside, a few of my inayopendelewa Horror-Sequels are "Final Destination V", "Saw II" and "The Grudge III". :P
My most inayopendelewa sequel to a horror movie is probably Scream 2. It is generally known that the sekunde movie was indeed better then the first and was praised kwa many critics. It is also a great series to me and that's why my 2nd inayopendelewa sequel is Scream 4. It is something old in a new decade. It is still scary as hell, but zaidi gory then the awali ones. It had a terrific plot and it was something enjoyable to watch. My third - and last - inayopendelewa sequel is probably I Still Know What wewe Did Last Summer. I upendo that series although the third one wasn't that good. I want a fourth film with the original cast/survivors of the first two. And Julie should survive everything. ISKWYDLS was as scary as the first one, although the first one was better. It had Sarah Michelle Gellar and she's a wonderful actress.
It's kinda hard for me to pick one. I've been a horror shabiki for a long time. I guess my juu three would have to be "A Nightmare on Elm Street," "Final Destination," and "Hellraiser." I've got lots zaidi but not enough time to orodha them all.
