who is this person who stole Superman's costume?

Rating: 4/10 (8 September 2016)

Spoiler: I will mention a scene to explain my reasoning, but it's not a major plot twist.
There were certain things I liked about this movie, but I want to get to one negative point, which unfortunately is fundamental for me that reflected this rating.
Superman is my favourite hero due to his positive outlook and immense compassion. Sadly, in this movie I do not feel like he is a very good person. He is very moody and mean spirited.
For example: Some jackass throws a beer can at Superman and he refrains from retaliating, but then he goes outside and maims that person's truck. This brings a completely different perspective on his personality because he does not refrain from punching back because he thinks it's wrong to use his power to hurt someone weaker. He refrains because he is afraid that he will be found out and it's also cowardly because he retaliates behind that person's back. This makes him look petty and selfish. Throughout this movie, every time we see him use his powers in minor ways, it's always to harm someone rather than being helpful (heating the handle to burn his teacher's hand, another example). This is not what Superman is about. This person is being a jerk in many small ways, which negatively defines his character and it's not even some grand bang scene or even the fact that he ends up breaking one of his taboos.
Superman is the type of person whose behaviour you can set as a good example for your kids. Would I tell my kids to behave like the person we see in this movie? Absolutely not. I do not like him as a person in this movie.
So, I don't know who this guys is, but he doesn't behave like Superman, in my opinion. Actually, I feel like my favourite hero is being slandered. ;(
I guess I should explain why the rating is 4 rather than 1. I felt that Superman's background and how he ends up on Earth was nicely modernised along with the special effects, plus making the villain grudge personal. I found it interesting how Krypton and his parents were represented, and phantom zone entry looked impressive too.
But, yea, the central pillar of Superman movies is Superman, and if don't like him as a person, then well, I can't give you a good rating.
