I am so fucking hype for this. It's almost impossible to believe that this is happening, that a real, proper cinematic adaptation of a Marvel comics crossover megaevent is coming and it's fucking huge! And yeah, the difference between this and Justice League is that this has been EARNED. It's been...what? Ten years and over a dozen marvel movies that have taken their time to world build and establish characters and set this ultra conflict up?
Unlike DC that wants to force-rush everything because they are painfully aware of how far behind they are.
