Best: Expanding the Shared Universe

Again, Justice League was the second step (although a much smaller step) in the right direction. It may lose the studio some money (many estimate $50 to $100 million), but it also presented an opportunity to rebuild everything starting from what was good in the first place.
Flashpoint should be the starting-off point. The Flash solo flick was teased in Justice League, as Barry Allen joined the force AND was set to discover new powers and abilities as he raced someone almost as fast as he is. Once they establish a multiverse, Warner Bros. can go in any direction it wants to.
Even the Deathstroke solo flick makes sense! As a matter of fact, in a multiverse, all announced projects make sense (even Superman: Red Son)!
Then there was the credit stinger, which revealed that the Injustice League, or the Legion of Doom, is coming. This is the studio’s chance to make a villain-oriented movie that’s better than any previous efforts.
Did the introduction of the Green Lanterns in the first battle against Steppenwolf indicate that a Green Lantern Corps movie is coming? We don’t know. But the Corps does exist! Originally, a credits scene was supposed to feature Kilowog and Tomar-Re, so it appears that Warner Bros. is seriously considering making this movie!
