The God Emperor of Mankind
Name me the villains in the MCU better than Zod and the Kryptonians?
MCU light-hearted tone absolutely works against them in the portrayal of their villains. Wack power levels work against them too. You never feel the stakes are that high compared to MoS.
Zod from the beginning is touted as the antagonist, his conflict with Kal-El from the start of the movie is established as personal because of his prior beef with Jor-El. It goes beyond the physical into the philosophical because Kal is a natural birth in a society that genetically engineers it's people, he is an abomination, antithesis to his memory of Krypton. It was a personal conflict that evolved organically in a relatively short span of time and wasn't shoehorned in like the fukking Mandarin. MCU is much more cookie-cutter villian. Zod is more nuanced than most of them. In his own way he is simply trying to revive his people. At the start of the film he is justified in his criticism of Krypton, you can feel a tinge of empathy for his situation.
This monologue alone >>>> anything the MCU has done besides maybe Thanos' threat to Ronan. (Micheal Shannon's acting in this movie was A1 but this scene especially).
This is a villian. This is how you introduce a villian.
This is how you establish the threat of consequences.
Faora on her own as a secondary villain is more terrifying than anything than anything the MCU has done (again, aside for maybe Thanos and Ronan), she went around slaughtering people and kicking Superman's ass. Look at her introduction to Kal:
He doesn't register as a threat at all. You don't have to monologue to establish a threat or a villain. A short, courteous sentence like this will do in some cases.
Ignore the fact that this scene is more epic and awe inspiring than anything the DCEU and MCU have done since (aside from Flight and the final fight). Focus on the interaction between Perry, Jenny and Lombard. This how you establish fear. Lombard's reluctance to help in face of the chaos is a small moment but beautifully done. The villians are sowing chaos, yes, but inspiring heroism in the common person as well.
To show fear and chaos of the common person in the face of disaster doesn't always have to be buildings crashing and thousands of unnamed people dying (though to be fair this film does that in spades) it can be singular moments like this, detached from the hero's predicament but a part of it at the same time.
Note, how eerily reminiscent the scene is of a woman giving birth.
Kal is outnumbered in this film by enemies who are just as strong as he is, are better fighters than he is and are smarter than he is. They are not punching bags like the Chitauri were or Ultrons robots. Faora is ruthless in her slaughter. The World Engine is terraforming the entire planet. The stakes are high. Midway through the movie you knew that humanity was done if Zod won, at the end of the movie you knew that if Zod won humanity was done.
The only time the MCU has even come close to this is maybe Thanos. Otherwise, no. You don't feel the stakes are particularity high.
Thanos (along with the Silver Surfer) is my favorite fictional character, I am going to wait and see if they can do this with Infinity War. MCU films are lots of fun. But it's villains are crap. Plots are shallow and any sense of background nuance is vacant.
Like I said MoS has better villains and done a better job at establishing a threat than anything MCU and DCEU have done since. Never mind other aspects of the film (fights, symbolism, music score, etc).
franchise needs a soft rema-reboo-quel
How and wtf were you expecting? It's an origin movie where they had to show how Superman became Superman with the morals he has. It would had been a shyt origin movie if they skip all that and went straight to the actions with zero character development.
