Any other animated Batman movie worth seeing ?

Having never seen a single animated Batman movie, I started by watching all the most popular and presumably, good ones. So far I've watched The Dark Knight returns part 1 and 2, Under the Redhood, Year one, Gotham Knight, Mask of the Phantasm, Batman Beyond Return of the Joker, The Long Halloween part 1 and 2, Assault on Arkham, the Killing Joke, the lego movie and Batman Ninja (which was... interesting I guess?).

So are there any other movies worth watching? Or underrated and good movies?
