It's brilliant IMO (I haven't seen the latest season but the one before ... season 3 did feel like it was losing its way a bit).
The thing with mainstream super hero stuff is that it seems to very much about supporting the status quo without really examining it. Generally, the MCU has been pretty guilty of this AFAICT. It's also why Winter Soldier is probably the best MCU film IMO ... Captain America becomes "the enemy" by standing up for his principles and destroys shield.
The Boys is about examining the status quo and so stands out massively compared to all of the other mainstream superhero stuff.
It's just too fucking dark for me. I don't dislike a gritty show necessarily but I couldn't make it through more than the first few episodes. It seemed good, but damn I have plenty of problems and shittiness in my real life, I like my entertainment to make me feel better, not worse. 😀
