I thought the first half of the episode held up very well, even turning to my girlfriend and remarking that this is better than most stuff being made today, film or otherwise.
Obviously, being made for a TV audience, esp. on of the late 60's it often repeats itself in dialogue and in dramatic beats, in case someone was out of the room or tuning in late.
It's a good, solid story, that could use some editing if it were trying to be pitched to a modern audience.
rgb, That was a great idea to look in the projection room, I'm sure I would have found a substandard projector in the NYC screening too. Even a good home projector would probably not be able to light up a screen that far away, really disappointing presentation.
