This movie feels like an extended episode from an animated show or an issue of a comic book. It's a self-contained story with a simple goal of delivering the message of hope and kindness.
The first half of the movie is a bit messy, events happen with almost no build-ups. For better or for worse, it really feels like grabbing a random comic book issue and reading it. After the first arc, the movie quickly gains focus and shows it's true strengths, it's amazing, well-written characters.
Edi Gathegi steals the show as Mr. Terrific, he's cool, funny, and unique. No superheroes in recent memory come close to his charisma in this movie. Nicholas Hoult's performance perfectly captures Lex Luthor's extreme evil and pettiness, setting a new standard for movie super villains. Rachel Brosnahan's Lois Lane feels like a new definitive cinematic version of the character, lovable and authentic. It can be said that the people surrounding Superman are the main characters of the film.
When it comes to political discussions, the movie doesn't dive too deep into the nuance or realism of the situations, it shows the audience its message, or Superman's ideology, in a very blunt and genuine way. The movie takes place in sort of a heightened reality, it expects you to turn up your suspension of disbelief like you would when you watch an episode of the superhero cartoon. It's flawed, cheesy, at times corny, but it's heart-felt, unapologetically comic book-y and fun.
