I think they should have a trilogy of adventures with batman and robin

First Film: Dick Grayson parents death; becomes robin; First battle with a classic villain

Second Film: Dick Becomes Nightwing, Introduce Jason Tood, Death at end of film. Villain is Joker(since he killed Jason)

Third: Introduce tim drake, Main villain is red hood.

And maybe many other films to follow
