The one that stuck with me enough for me to recall it seventeen years later was the bawdy punning Hamlet exchanges with Rosencrantz and Guildenstern: I remember the scene working very well, and being annoyed that they didn't just keep going.

But this is because the first performance of Hamlet I ever saw, on stage or screen, was Branagh's, and I watched it something like three or four times before I ever saw another. So in general my subconscious is convinced that ALL THE LINES SHOULD BE THERE, and it is annoyed at every other production for not being four hours long.
