Zack was going to make an epic to build off MOS and BVS, but they brought Joss in to wash it all away and make a generic chuckle fest. Still upset about what Joss did to Batman. "I don't not like you." "Wow, he's tall."
They wiped away all of Steppenwolf's development, the Kryptonian scout ship scenes, Supes meeting Alfred, Green Lantern cameos, and took out a lot of the history lesson. The deleted scenes (like 80 Cyborg ones
) that were leaked. The parts from the trailers that didn't make the theatrical release. You can tell the difference in filmmaking too. Y'all see that Ma Kent and Lois scene at the Daily Planet? With the cussing grandma and the "thirsty" joke. Looks like a TV show. The best parts were the team working together like the sewer scene.
