So this was done THREE times?? Two Alfred Hitchcocks and a Ray Bradbury Theatre.
Also…what does Bradbury have against carnival sideshows?
I just have to say that I love threads like this – lots of interesting mentions of things that I haven’t seen before, and that sound ideal just in time for Halloween! Keep 'em coming! 
On the flip side, you have The Simpsons’ Treehouse of Horror episodes. The first ten years or so were almost brilliant. You sometimes get the feeling they kept making weekly episodes just so they could put all their “oomph” into the Hallowe’en stories.
Mr. Burns: Hmm… that’s odd, usually the blood gets off at the second floor! 
I saw this when I was in college and it spooked the hell outta me.
Doctor Who – Blink – the original weeping angels episode. Angel statues that move (and kill) whenever you’re not looking directly at them.
I’m getting there – just finished the second episode. So far it seems like a very good series and has apparently won awards, but it also seems like a complete departure from the Shirley Jackson book or the 1963 film which was very faithful to the book. That’s fine with me, but it’s odd seeing it billed as “based on the book by Shirley Jackson”. Indeed there is almost nothing in the first two episodes that resembles the book.
A grave robbery goes poorly.
We felt like it really picked up around the fourth episode, to be honest.
I’ll go with another Twilight Zone episode, Twenty Two. Watching Spock’s fiance saying “Room for one more, honey” still scares the crap out of me.
Here’s the condensed version
Just to add, I’ve now watched “The Bent-Neck Lady”, and it really is very well done and (if I may use the term) haunting. As an added bonus, I watched episodes 3, 4, and 5 in sequence last night, and by the time episode 5 started it was about 3 AM – a perfect time for one of the great episodes of an extraordinary horror series.
For those interested in seeing it, I’d advise starting at the first episode and moving through sequentially. First of all the whole series is excellent, and secondly, it’s quite a complex plot, with shifts back and forth through different time periods, and you really need the background to understand and appreciate “The Bent-Neck Lady”.
