They were fairly banal. Largely because the format was designed that way: the content was delivered in a purely informational format by speakers who were expected to stick to the material provided. The only time I can remember people perking up was when there were announcements to be made; even if they weren't dramatic, they were at least a change of pace and something that we could process mentally. Otherwise, the meetings are the equivalent of writing a phrase 100 times on a chalkboard, which is the sort of thing that was used to punish misbehaving schoolchildren.
People went because they had to, and to the extent that we enjoyed the meeting, it was because we got to get together with friends and have a bit of conversation before and after the meeting itself.
