The boys is more straight forward and easy to follow so I'd say it's more enjoyable. Watchmen is really deep and complex even though I don't know what the fuck is going in half the time I still feel like it's is a high quality TV show.
Watchmen is gritty like the Wire but the Boys is not some mindless superhero show. It’s deep as shit and really goes over a lot of societal issues and behaviors, probably more so than Watchmen which focuses mostly on racism. The Boys goes a step further and looks at power distribution, how it influences behavior, morals, choices, etc.
I know opinions can be wildly different, but I dont get this one The Boys is a cock and balls slapstick superficial comedy compared this crazy detailed complex level of creative story.
The conclusion of the entire Boys season is easily outdone by any single one of watchmens better episodes so far.
I'm not trying to compare or pit them against each other, I enjoy and look forward to both of them. But dont get how one can process two of vastly different levels of storytelling like these two and not realized which one is more rewarding or impressive.
