I would say this show is overall enjoyable. It definitely has some flaws but surpassed my expectations. It's better than many shows of it's kind. Such as The Boys or Gen V.
My expectations for this show were pretty low. We've all seen the, "What if superheroes were not good?" scenario. We get it. It's been played out. This show does manage to take a somewhat unique perspective on it though.
Stuff I liked
Mark Grayson is Invincible and he's a fairly likeable character. He's a teenager who is just starting to inherit superpowers from his father, Omni Man. I really enjoyed seeing his desire to help people and save humanity. I also appreciate what the animators did with his character. The flying and fighting feels very shaky and inexperienced. That's hard to communicate in animation so that was cool to see.
It has a stellar voice cast. Features the likes of JK Simmons, Stephen Yeung, Mark Hammill, and many other familiar names. They all do a really good job.
I really enjoyed the overall mystery with these murders. It was very interesting and is pretty much what kept me watching, even with the flaws in the show.
Things I didn't like
The violence in the show at times felt excessive. I can appreciate being real, it gets to a point in this show where it just feels kind of numbing. You see guts and blood flying everywhere in almost every action scene. At first it's really shocking and did a good job at getting the point across, but eventually it loses it's value for me.
There is some gay stuff. Hollywood is promoting woke politics in entertainment and this show attempts to make it seem normal.
