When I was a kid, I used to watch The Twilight Zone and The Outer Limits with my dad. I watched all the remakes, but the original Zone with Serling will always be the best for me. I felt that you managed to capture that feeling of despair and otherwordlyness.
Pd: By playing the first 5 minutes, I thought that it was an adaptation of sorts of Nightmare at 20.000ft. I was gladly surprised :)
