Drupada wanted a son who could kill Drona, and got him. After that, w/o his asking, he got a daughter as well, and it was announced that she'd be the cause of the destruction of the Kurus.
So this serial wants to blacken Drupada's character? But it's not like they show Drona in that good a light, so why bother? Aside from his grudge against Drona, Drupada was not an evil person. And his support to the Pandavas was genuine, once they married Draupadi. And he designed that swayamvara so that someone like Arjun would win.
