WSJ reported that KT wanted this film to be under 2 hours. Then we get a movie that is literally 1 minute shy of two hours. You don't think they cut a lot of stuff out of the movie?
I think you need to ask yourself: After complaints about BVS' length and pacing, would WB really have mandated or allowed a 2 and a half hour cut of JUSTICE LEAGUE, or whether they would have allowed some of the rumored types of deleted scenes to be in JUSTICE LEAGUE, given major complaints about scenes of that type in BVS.
I think you need to ask, if the movie was originally planned to be shorter, say 2:15, or 2:20, just how much extra stuff was in the film, and how effective would that stuff have been in the narrative?
And I think you need to look at the message that was coming from WB and the creators and actors after BVS; namely that they were accelerating the hope and optimism (translation: more fun, less ponderous navel gazing) and that the next film would be simpler, and more straightforward.
Heck, look at BvS, lots was cut out of the TC. You are trying to apply logic to what WB has been doing with the DCEU, but they have been following their own logic.
I'm not sure what that means.
They didn't cut three main characters story arcs and multiple battle sequences out of the theatrical cut in BVS. They cut connective tissue type stuff. What's being implied when it comes to JUSTICE LEAGUE is they cut multiple backstories, at least one grand battle sequence, and effects-heavy dream sequences.
I think some of you are approaching this from the standpoint of an unrealistic perception of what the film likely WAS prior to WB's "meddling" during filming.
We can make some educated guesses about what was actually shot for this film based on trailers and the existing film, but I think the perception people have now is based on a plethora of rumors, many of which have proven to be outright false.
The tangible deleted scenes that we know existed are either brief action/power sequences that are not a deep dive into the origins of the characters, the Atlantis scene with Vulko which would flesh out the politics of Atlantis a bit, Superman in the cave/black suit, a different version of the Kent farm scene, and potentially the League VS Superman battle sequence. Not too many of these significantly alter the narrative of the existing film, near as I can tell. They feature alternate dialogue, and in the case of the Vulko scene, would serve as a further AQUAMAN tease.
But hey, believe what you want.
