I can't understand why some people think that additional scenes to a bloated movie are going to solve the film's problems.
Eh, I think the movie was less bloated as much as it was overloaded. Too much stuff in the movie and not enough time given to properly develop each storyline.
The fix to this is either:
1) You cut a ton of subplots/characters out of the movie
2) You make the movie much longer and more properly develop everything
So an optimistic person could hope this the second option and makes it a better film.
Like my first impression walking out of BvS was "movie was bad, should've been split into a 2 part film"
