I have to disagree. There are a lot of time where adding in scenes that were cut can improve a film a lot. We can get more depth to plotlines and characters that were underdeveloped in the theatrical version, and it can put in explanations for things that didn't make sense in the theatrical version. Some movies are just bad, and no amount of added footage can fix that, but there are a lot of movies that can be greatly improved just by adding in a bit more footage that was cut from the theatrical version. I do think BvS will be in the later category, the trailer for the extended version already shows footage that looks like it will help some of my issues I had with Superman/Clark's role.
