Other than being shocking and edgy.
Watchmen has themes, The Boys TV show has themes, this doesn’t really have any or am I too stupid to figure it out.
The boys is substantially more shallow than Invincible lol
You a TV only?
I think the problem is you are focusing too much on more dark and cynic stories like watchman and the boys.
Invincible at his heart in the comic and at for now in the TV show is about being truly a hero like most classic super hero comics like spider man and batman. It just have a more serious tone towards how this lvl of power translates to a world filled with fragile humans.
But the theme is doing what’s right No matter the cost, standing up for what is right. Even having the strength to forgive enemies and build a better future. The entire comic revolves around mark struggling to keep being a hero.
Finding yourself. Every single hero is going through a journey to figure out who they are and what they want to be. How painfully obvious does it need to be when they all mention it constantly?
The boys is a critique of the superhero genre, while itself is now playing into what it critiques the genre for (best example: spin-off show). Invincible is more of a standard superhero story, finding yourself, standing up for what’s right regardless of the cost.
Pretty sure you just haven’t figured them out, some of the themes in invincible coincide with themes in The Boys as well, and then there’s even more on top of those. They’re all fairly easy to notice too, for instance, both The Boys and Invincible explore what level of wrong doing can be justified if it’s done for a good purpose. Also it’s odd that you chose The Boys tv show as an example of having themes, yeah it does, but it also has far more moments intended for shock value than invincible does
Finding yourself.
In season one, Mark gets his superpowers and wants to prove himself. When Omni-Man tells Mark what his true purpose was, he unironically gave Mark another one in stopping his dad from taking over the world.
Season two so far has Mark try to not be his dad and actively goes out to save people. The comics have more themes, but I don’t want to spoil anything unless you read the comics.
