I don't find anything depressing about it. At all. Moments are sad, of course, and some incredibly so. When I see a wonderful production of ACL, I feel true catharsis.
I'll only one sad moment here I didn't see already mentioned: Diana Morales. While her song is largely comedic, I find the ending truly heartbreaking.
I enjoy the documentary (Every Little Step) and always miss that character's casting not being shown. I assume there was no story there.
If we're not having fun, then why are we doing it?
