Sorry for taking so extremely long to reply. I myself had forgotten about making that post **embarrassed face**
I have watched all titles mentioned by you, except the Tomie films. Many of them are comedies, which kind of spoils it for me. Making comedies about vampires and reincarnation just does not work for me :P Dead Again was pretty good, though that uncanny feel of Reincarnation of Peter Proud was marred by the hyper-dramatics. Birth was also really good, but monochromatically depressing in the end. The one film that I kind of disliked is Audrey Rose. It is about reincarnation, seemed like, but the things they said there, especially Hopkins going on and on about how 1 billion Indians could not go wrong (I myself am one) was really annoying. Most Indians do not seriously care about or believe in such things, though I admit they are somewhat easy to convince and confuse when it comes to matters of the afterlife. But in short, I did not really get the point. There was nothing creepy. Seemed like some adults, while repeating the same phrases to each other, prolonged a little girl's suffering, and ultimately killed her.
@ the others:
You guys have made some solid recommendations that I know nothing about, which is already very exciting to me :D I will find them all and watch them and come back to this thread :) I love this school of thought that lead to the making of films like Reincarnation of Peter Proud. It no longer happens now. I also feel the poor quality of the film adds to the creepiness and atmospherics. If the film could be remastered to 1080p and 7.1 surround, it would kill a lot of the creepiness. What say guys?
