Yes. Lets turn every movie into Marvel fluff. This is so classic hollywood. Chasing money, chasing success at the expense of storytelling.
BvS was a very flawed film, but its problem was not its tone. TDK was much darker... i was exhausted after the movie... but it is just a better movie. The pacing is perfect. the editing keeps the movie focused on the three main characters. the character development for Harvey and Bruce Wayne, the character motivations for Rachel, Lucius, Alfred and even Gordon were beautifully realized.
Zach's BvS is all over the place. The editing is very jarring which makes the first half of the movie feel like a slog. His superman mopes around the entire movie barely even talking. His Batman was great, but kills indiscriminately which makes no sense considering all the Batman villain in Suicide Squad are obviously alive. The finale was visually amazing, but lacked any kind of emotional weight TDK's ending had.
They need a good script with proper character motivations, not a funny script that takes away all the tension at the end of the movie like Marvel movies. They need a good director. Zach snyder makes beautiful looking movies with some awesome action scenes but he is not a good director. He's basically a talented Michael Bay.
i am one of the few people who liked BvS despite its flaws hoping that they would be fixed in the sequel, but this is not what i was hoping for.
