Broadway musicals first:
"1776" is my number one, no question. I used to like "Jesus Christ Superstar", with a few qualifications, but have no idea how I'd feel about it now. I always wanted to like the "Fiddler on the Roof" film more than I actually ended up liking it (this one needs to be revisited at a time when I'm in just the right mood for it). I do like "Hair" more than I used to. Believe it or not, I've never seen "Little Shop".
I dunno, it's tough. Whatever their various flaws, the filmed musicals of the '50s/'60s are the ones that ring my bell, now and forever.
Original Disney stuff, etc., no problem:
Bedknobs and Broomsticks
The Lion King
Beauty and the Beast
The Hunchback of Notre Dame
The Little Mermaid
South Park: Bigger Longer & Uncut
