I will begin by saying this, Batman V Superman is a good Superhero film. It contains many references to classic DC Story lines and even some modern ones as well. I will say this as well, if you are not versed in comic book lore nor if you are not invested in these characters like many comic book fans (myself included) you will not be able to understand the emotional grasp and turmoil that these characters face within the film. If you are not a deep comic book fan and simply only watch the films, or worse yet if you are expecting a comic book movie like the MCU films, then you will not enjoy the film. The film is dark and is involved with some of the heaviest DC story lines of all time. The movie is not fun nor funny, it is a serious drama.
This film is not perfect and has both good and bad things. I will address the good first for you should see the film. The acting is on point and I mean all of the acting. Ben Affleck hands down is the best Bruce Wayne/Batman to date. We see every aspect of the character portrayed through Ben, including the combat, which is far different than Nolan's Dark Knight Trilogy. Gal Gadot as Diana Prince/Wonder Woman steals the show. She is one of the best aspects of the film, even with such little screen time. Henry Cavill as Clark Kent/Superman once again does a great performance and he really deserves more recognition. Jeremy Irons as Alfred Pennyworth is great. He is so much like the modern Alfred in the comics than any other Alfred before him. Amy Adams as Lois Lane does a decent job, but could be better (I didn't like her in Man Of Steel). Finally Jesse Eisenberg as Lex Luthor. He has been getting a lot of flack for his role in the film. People have called him annoying in the film. But after seeing the film, I see the madness of the character and it adds a whole new spin on Lex and to tell you the truth, he is probably THE MOST IMPORTANT CHARACTER IN THE FILM. As Amy Adams' Lois Lane said in the trailer "You're Psychotic!"
Now comes the bad aspects. THE FILM IS BORING. Why is the film boring you ask? For one reason. There is no tone in the film. In most films you get a feeling, whether is fear, excitement, sadness, something. You feel some sort of an emotion, in part due to the characters, the plot and the music. In the film we know the back stories of the characters and their reasoning so its not the characters that's the problem. Its in the form of a lack of a plot and the lack of tonal music or score. These two elements were gravely lacking in the film, which lead to the boredom and at times confusion within the film.
On a final note, the effects were amazing, the acting was well done, and it captured a lot of classic DC Comics story lines, but tone was missing which lead to boredom and an aggravation due to its long run time. Overall the film deserves a 6.5 out of 10. A weak start for the DCEU.
