[neverending]

The original stands high above the others. IMO the 78 version has dated more than the original. The original has a marvelous ambiguity at the end, where you're not sure what will happen. The last shot of the 78 version gives everything away and ruins the effect- and ruins the whole movie.

I know I've seen the Ferara version, but I honestly can't remember anything about it, which is strange because I'm a Ferara fan.
