I finally started watching this. I’ve avoided the show because I heard it was really violent and crude, but I’ve seen glowing reviews of its character work and plotlines, so I finally decided to give it a try. It definitely is far more gory than I care for, and I avert my eyes a lot, but otherwise it’s a damn impressive show, with mostly effective humor and fantastic, nuanced character work. There have been some very funny moments, but also some incredibly poignant, moving, and dramatically powerful moments. It’s the first time I’ve liked Kaley Cuoco in anything; she’s surprisingly good as Harley. (But the last -- really, the only previous -- thing I saw her in was the original Charmed, which was 14 years ago, so long that they’ve already rebooted it.) Lake Bell is fantastic as the best version of Poison Ivy I’ve ever seen. And Diedrich Bader is easily the best Batman voice actor not named “Kevin.” I don't much care for the show's version of Jim Gordon, though.
The animation is also quite good -- I'd say it's even better than the animated movies DC's been doing lately. The character designs are excellent, especially Harley and Ivy. A good Batman design too. (I'm amused that Alfred is basically David Niven.) And the climactic action sequence this past week was really impressive.
I just wish I'd started a week later so I didn't have to wait for the season 2 finale. If that makes any sense.
Alan Tudyk seems to be doing kind of a Hans Conreid-ish sort of thing with his Joker voice. It's not exactly an impression, but it has similar elements.
I never got the whole "romance ruins a friendship" thing. I'd think that friendship would make it easier to accept and forgive anything that went wrong with the romance. And I don't see how a romantic relationship can really work if friendship isn't part of it.
