Come on, it's a cartoon which seems to be run on the premise that it doesn't need to make sense, so long as it is AWESOME. It is completely and utterly ridiculously silly, and that is why it is brilliant.
I mean, this week's episode contained my darling Jaime (♥) in the teaser in all his lulzy adorkability, complete with snarking at his scarab/suit while he fought, a robot trying to work out what the Christmas spirit is, shout outs to all sorts of dodgy B-movies, Batman getting a "World's Greatest Detective" for Christmas, Batman beating up Santa, Batdickery, unexpected heartwarming endings, and even more unexpected tragic flashbacks.
It was ridiculous and silly and surprisingly touching. But mostly awesome.
And that is why everyone should watch this show. Look, have some Blue Beetle being lulzy to see why I love it.
(Also, I know some spoilers for an episode later this series which will be freaking win, and I can't wait until fandom hears)
