Corpse Bride was fine, typical Tim Burton whimsy, cute spooky characters and pretty cool visuals. It was very similar to his Nightmare Before Christmas, just in overall tone and style,  no complaints.

Batman & Harley Quinn, meh, it was entertaining, but it just did not fit the tone of the Animated Series continuity in which it was set. Yeah, I actually care about the continuity of an animated batman show, I have no life, I know. You don't have to point it out. 

Back on topic, it seemed more like it wanted to be an Adam West style, funny, corny batman as opposed to BTAS gritty and dark style. But that doesn't work. BTAS has a popular cult following because of its noir style and seriousness. Trying to turn it into campy shlock just pisses the fan base off. Rant Over.
