I should preface this by saying I've not watched a network sitcom since Seinfeld (unless Arrested Development counts) til this, but the DCU setting triggered my compulsion. It is exactly as bad as I imagined. I can stomach it, but then again I'm watching at double speed so it's basically 10 minutes.
The only real DC characters so far are Jack O' Lantern (a villain version) and Crimson Fox, who for some reason has super strength. But then it occurred to me that despite having read the full run of the Giffen/Dematteis Justice League years when she was around a lot, I wasn't entirely sure she didn't have super strength in the comics, and can't really put my finger on what her powers were apart from being French and being twins.
