A couple things really bother me

In a few episodes, villains like the Joker and Catwoman are shown in jail, yet they are in their costumes and make up in the jail cell. This makes no sense. Everyone knows while in jail, you are wearing a prison outfit. Another thing that bothers me is quite often the villains capture Batman and Robin and no one removes their masks. Why? Sounds like I found a pair of plot holes in this otherwise well written series
