I just arrived in the US yesterday, and this pretty baby was waiting for me. The discs are the same as the previously released season sets, but it does include a bonus disc with a Batman animation history documentary.
If you don’t already own the individual sets, I highly recommend this set.
The Man Who Killed Batman
The Demon’s Quest Part 1.
Batman: Mad Love, which was of course adapted into the great Batman TAS episode of the same name.
I don’t quite know what to write about it, to be honest. It’s just an excellent Batman comic about the origin of Harley Quinn.
The HC comes with some great back up tales, of which my favourite is Two Of A Kind, a great Two Face tale.
So, yes, you should own this.
