"Take note of the PG-13 rating. This is not a film for children. It starts out showing the Joker beating Robin to death with a crowbar, then ultimately blowing him up and killing him. This is straight out of the classic "Death in the Family" comics right down to the imagery. The violence continues as we see the Red Hood deliver a bag full of severed heads to mob leaders, characters getting shot point blank by Joker, red blood spatters on walls as people’s heads are shot, and more. It’s nothing you don’t see in the movies, but it’s kind of surprising if all you’ve ever seen of animated Batman is Timm’s revered TV series."
