Eh, unlike some shows (like Young Justice and GL:TAS) Beware the Batman would have died anyway. it looked cheap, with a dead city even for a CG cartoon and bad character designs overall (for example, Batman's design literally didn't allow them to take off his mask on screen, because his head is shaped so radically different then the head on the Bruce Wayne model). Its writing also wasn't good. Its nice to say "We're going with obscure villains", but when you do it badly you just make people want Joker, Riddler, etc even more. I love obscure DC villains, but its hard to sell even a comic nerd like me on villains like Magpie, Anarky, Professor Pyg and Silver Monkey being the main threats. have them in there, sure, but you need to sprinkle in the big bads even if your writing is great, and gradually get people interested in obscure or new villains (like how B:TAS didn't just start the show with Mr. freeze, harley, etc).
