Just like the whole season, the episode was honestly rushed. I was hoping for more Batman since they said that it would have more but he's only fully shown in the final shot which was disappointing. They only got Mr. J to actually come back in the end but even then, he was defeated with 3 batarangs, no fight scene or anything. Riddler and Penguin were there and their suits were cool but they were focused on way too much. I was expecting them to have like 10 minutes of screentime before not being shown again while Mr. J comes in. No Riddler cane or cat ears, sadly. Idk why they shaved Gordon's moustache so quick, he could've kept it for the whole episode, it wouldn't have been a problem. In general, the whole season was just rushed, there were so many villains who didn't have their arcs complete. They only mention Mr. Freeze and Firefly, no sign of Man Bat, no Lady Shiva, Scarecrow was barely in the first episode, Jane Doe/Ventriloquist/Magpie were all killed in one episode which was disappointing.
The last 3 episodes were the most rushed tbh, if they had used the extra two episodes to develop the story, it would've been better, however, those extra two episodes were filmed after "I Am Bane" and "They Did What?" so it wouldn't have worked. Bane and Nyssa were kinda just thrown in there during the last 2 episodes (before the finale) while Jeremiah's S5 arc finished too quick. With 22 episodes, this season could've been better, it was like all action and barely any proper interactions.
