I don't know why some people are hating on this as a rip-off of the Boys? (I like the Boys but pretty sure Invincible is the older comics of the two so if anything it's the other way round).
The series is great and has a nice balance between being light-hearted and making you think. You don't really think about certain points when watching your generic superhero series (they'd definitely have some form of PTSD IRL).
I loved it and it's worth watching the first episode if you like animated action and more 'realism' in a superhero series.
