Being a purist ...
... I actually do not like colorized film. It looks fake and contrived.
Sandy, thank you very much for that scientific analysis of why so may young people refuse to watch black and white programming. I rather enjoy it myself, and I often ask myself WHY I like those old movies so much, given that such an important aspect of the visual experience is lacking.
That said, I think that same principle could apply to why I find it difficult to get into old radio programs (or even newer radio programs!). I once dated a guy who listened to "A Prarie Home Companion" religiously, and I have to admit sitting through it for me felt like absolute torture. Could it be that because I didn't grow up listening to radio "stories", my brain was wired only to process stories that provided both audio and visual representation?
Subtitles. I absolutely despise them. I find I'm missing a lot of the visuals because I'm too busy reading the words.
And thank you (someone) for mentioning the mumbling that seems to pass these days for acting. WTF?? SPEAK UP!! And no, I'm not going deaf, because I can hear the damn music and sound effects just fine -- they even overpower the dialogue at times. I'm getting tired of hitting *stop* ... *rewind* ... *play* ... several times sometimes ... to make out what the hell they're saying.
And one more pet peeve: printed material in the movies or on TV. Back in the day they'd do a nice tight shot of the note or letter or whatever, and STAY ON IT long enough for us to actually read it. Or they'd have someone narrate over top of it. Enough with these three-second shots of printed material that we need to process in order to understand the plot line!
