WB really should have made just 2, Batman Beyond DVD sets having 26 episodes in each rather then making it 3 sets. It was great seeing these last 13 episodes again of the series. The two part episode "The Call" gives a hint to Terry's biological connection to Bruce Wayne. The DVD extras are very limited. So as long as you just want to watch the episodes then you'll be happy. The construction of the box is very basic not as nice as season 2.
What's great about it: the final 13 episodes including the first JLU of batman beyond
What's not so great: Box design is a bit basic, not many extras
