Guess should update this thread a bit
First order of business, Batman: Return of the Joker is THIS week's movie.
Due to some suggestions, I decided to add Superman/Batman: World's Finest last week, never made it into the thread.
I'm sorry... with that said.
The Batman/Superman Movie: World's Finest
The first team-up between the Man of Steel and the Dark Knight from the TAS episodes.
The "movie" consists of 3 episodes of the Superman: TAS and one of the reasons was reluctant to include it on my list.
With that said, it does work pretty well on its own. Most people know who the major players are, but as a recap, Superman and Batman are our heroes and Luthor and The Joker are our villains,
Their dynamic is fine, but I think the chemistry/interactions between Harley and Mercy is much better. Though the Joker/Luthor relations shows up again in Justice League.
The threat is well all over the place as it pretty much acts like 3 mini stories connected.
The short and simple of it really is if you own Superman: TAS check it out, but wouldn't go out of my way to find it.
