Is there no sense of nostalgia that some former JWs might channel? Of course, I'd imagine that there'd be more triggered by this stuff than those who might smile fondly at a positive memory of such gatherings. So, to each his own, I guess.
Edited to add: I myself, even though I've not so much as attended a meeting in a Kingdom Hall, find these meetings and other broadcasts by the WT to be too heavy going and oppressive to actually sit through. But I was never born and raised in that particular briar patch.
