What’s the antithesis of Arrested Development, Firefly or The Big Lebowski? Those may never have ‘found their audience’ but over time seemed to recognised by everyone. What are the deep cuts that you liked but it feels like everyone has completely forgotten they even existed.
Preacher. https://m.imdb.com/title/tt5016504/
There are shockingly deep themes in the series: modern cults, the nature of good and evil, doing good with bad intentions and doing evil with good intentions, after effects of suicide, purity of karma, the naivete of Christianity, the creation of weapons too powerful for their creators, friendship and forgiveness and guilt, and so much more.
I honestly think it’s one of the best series ever created and doesn’t receive the recognition it deserves.
