Just my 2cents on BATB.
I used to love BATB, mostly because it was self-satirizing and generally hilarious - there are some real "meta" episodes (such as the Music Master, Strangest Cases and final episodes).
Really, I think an Aquaman serious would have been a fantastic...oops I mean "OUT-RAGEOUS !" follow on.
What made BATB great was that it took the piss out of itself, along with the entire superhero genre - but also did fan-service to some of the greatest superhero stories ever.
In fact, in some ways BATB did a better version of the Batman v Superman fight from Dark Knight Returns, than the recent live-action crap-fest
I get that some probably didn't like the campy tone, but BATB managed to keep the balance of camp and seriousness pretty reasonable.
Anyway, I miss BATB (of course I have a few episodes on DVD, and once in a while pull them out for a laugh).
