The thing I hated the most about the way JL handwaved story was Clark's return.
How in the hell was he able to just come back happily to the planet? They ran an article about him dying at the same time with Superman, and now are they going to run a story about his return at the same time as Superman's?
Terrio surely wrote a good explanation. But Whedon.
Whedon didn't care about internal consistency in the movie at all. I mean it was obvious from the opening scene with the para-demon. That scene was cool, but it made no sense. It also makes the next scene, where Bruce goes to meet Arthur just seem weird. I mean, look at the visual language of Bruce arriving. From the first trailer I knew that Bruce on the horse was probably going to be the first time we saw him in the movie. It makes sense, he's spent months trying to track down Aquaman, he has a beard, and is in a barely surviving fishing village. With Whedon's changes it seems like he grew a beard in like a day flew up north, then flew back.
There is also the problem of Cyborg's origin, which was totally screwed up in JL, also in a Whedon scene. The accident had to have happened at least a couple of weeks before Superman's death, and the mother box was already at least somewhat active at that point. In JL it happened AFTER Superman died, and if you look at the footage, there is a lot more of Victor left when he's being created, like he has a full torso. That was NOT the case before. It was a change for no good reason, just that Joss had no care at all for continuity.
Which is probably my biggest issue. Say what you will about Snyder, but he has a great eye for detail. That's what was missing here. I still like JL, quite a bit. And hey, some of Whedon's additions were great, but I would have loved to have seen Snyder's cut, with just enough of the Whedon character work to keep the dialogue fresh.
Probably the same as the comics, injured in metropolis rubble had amnesia.
The thing is they buried an actual body. One that was seen by friends and family. Then again, I thought the funeral for Clark was a BAD idea in how it was handled in BvS, one of my least favorite parts in that movie, especially when looking at what it would do to the lore going forward.
