When I was a boy, I found a book called Monumentally Mad, which was a publication of Mad Magazine. It was intended for adults, had lots of PG-13 language, and I always felt a bit worried that my parents would discover me reading the book and I'd be in trouble. This particular book gave me those same feelings.
This is the most "adult" and arguably pornographic comic I've read by a substantial margin. It's not all immaturity and vulgarity - there are some strips which function as societal commentary and criticism of seemingly everything. The author is clearly educated, nihilistic, and (at least a bit) cynical.
Unfortunately a lot of the author's observations/thoughts lack much in the way of profundity and are the sort of things that most people think about in high school or their early 20's. Much of it seems to be edgy for the sake of being edgy, or (worse yet) the sort of thoughts that a fair number of people have but few would venture to write down. This is not because writing down these thoughts or observations is "brave" or "irreverent", but because the thoughts are not actually worth anything. They are the meaningless (and occasionally violent) daydreams that plague seemingly all young men but don't need to be expressed in art. It's the literary equivalent of telling someone about a dream you had.
Strangely the bit I enjoyed the most was a one-page garbage story called "Needledick The Bugfucker", which was about a kid named Needledick who, well... fucks bugs. It was useless filth, but it was enjoyable because there was no attempt to impose any sort of social commentary or other self-inserts. It was just a comical and stupid story that made me laugh.
There is the possibility that I just "don't get" this type of art, but I don't necessarily think that's the case. I think it appeals to people who are less intelligent than the author and see him as a witty satirist. To be clear, the author IS a witty satirist, but this work is not objectively good. It feels like an underachievement.
