I Won't Lie...
This does look like it'll be entertaining. Still, my biggest issue is with the premise that the Worlds' Greatest Superhero has to take a backseat to Baman. They keep saying that it's a Batman movie that'll open up into a broader DCCU. But what about Superman? Why is his story relegated to the background to introduce yet another incarnation of the world's current most popular hero and overused Deus Ex Utility Belt? I wasn't in love with MOS but I wanted to see Superman get a chance to actually be Superman and not just a super-powered Robin that Batman has to pull by the ear through an adventure.
