This version is really R-rated by name only. There isn't justification for it to be R; it seems like more of a marketing ploy to capitalize on the audience that made "Deadpool" so successful. There wasn't any added sex or nudity; there was only one f-word added, which isn't cause for an R-rating; the violence wasn't really exaggerated. The majority of the scenes added in the Ultimate Edition were character or plot development, not action scenes.
There were some major improvements in this edit over the theatrical release. The biggest improvements were an increase in justification of the actions of Lex Luthor and Senator Finch. Extended scenes in Africa explain the suspicions held against Superman. Other scenes explain Lex Luthor's past and his motives for his actions. Eisenberg's portrayal of Lex Luthor was one of the few parts that I really liked in the theatrical version, and this makes him even better. While I acknowledge that Eisenberg's Luthor is not the same Luthor from the comics, I think that it retained many of the character's qualities, including his meticulous plotting and need to orchestrate chaos. There are also added subplots involving Lois Lane, which allow her to shine more in this cut of the film. As a whole, the film feels much less hectic, and seems to find its identity more, with it feeling like more of a Superman movie with Batman and Lex Luthor as antagonists, leading up to the main battle. The film also included new foreshadowing to a plot involving Darkseid, in addition to the original foreshadowing to a plot similar to the video game "Injustice".
Regardless, there are still many problems that were unable to be fixed in this film. The film still tries to be overly philosophical with the surreal dream sequences, including what seems to be Snyder's audition to direct the next "Mad Max" film. Snyder's divination of Superman is a novel idea at first, leading to some really excellent cinematography, however it gets old quickly. Doomsday still remains unfixed, but I didn't foresee that being fixed.
So overall, I ended up liking "Batman v Superman: Dawn of Justice (Ultimate Edition)". It corrected quite a few of the mistakes from the original film that made it muddled and confusing, however it was still unable to fix some of the issues. Ultimately, this film was a much better and much more enjoyable film experience than the theatrical version.
