The way Deathstroke was integrated in the show was great and took advantage of the show's premise. LOVED the reveals on his past and identity. After the bitter taste that the terrible version of him in
Son of Batman left, it's nice to have a great animated Deathstroke once again.
The team-up with Manhunter was also fun. Quite an obscure character for them to choose. The team-up with Oracle was a also fun, and Killer Croc once again was an enjoyable villain. The overall Outsiders team-up for the finale was unexpected but rewarding. I was glad we got to see the team more or less form when it could have been saved for the second season. I was also glad they used Man-Bat as an ally, since that seems to be forgotten a lot, and is a fresh way to present this famous Batman character.
I also liked the compromise they did to make Professor Pyg a bit more like his comic book version. I just hope he gets more victims for his experiments next times beyond just Man-Bat.
My one big disappointment was how Harvey Dent was handled. I get that they wanted to do a different spin on him by making him a "two-faced" politician, but they made him too unlikable, and it removes a lot of tragedy of his incident. It's also a shame he was only teased, even after his disfigurement. If he was being saved as a season two villain, we could have at least seen his disfigured face, but the closes we get is his mis-matched eyes under the bandages. His voice sounded good, though.
