I'm of the opinion that the majority of the film was written by Goyer and Chris Terrio pretty much worked on the Batman scenes, which is why the writing for Batman was much better.
Goyer has the cheesiest lines. "Your a monster Zod & I'm going to stop you" is terrible & the line "I'm take you in without breaking you" is just as bad.
Goyer likes to beat themes over the head and we got this constantly throughout BvS.
I didn't like BvS in theaters, especially the handling of Superman, his motivations & some of his actions just didn't make sense. After watching the UE, it was a lot better and made a lot more sense and I actually really enjoyed the UE version of the movie.
Snyder's DC movies just don't flow well, as some one pointed out he likes cool moments but they don't hold the same emotional weight because they are superficial.
The music also didn't help either, the various themes for each character took me out of the movie. The only exception was when Superman was on screen because the theme is understated, so it fitted in with the score of the movie.
I have more hope for the JL because Terrio is writing it exclusively.
BvS = 4/10
UE = 7.5/10
