If I had to pick just a couple, then Twin Peaks and The Prisoner. Both have interesting styles, both keep you asking questions rather than spoonfeeding answers, both were ahead of their time.
Batman: TAS was and is dope. The entire DCAU is the best adaptation of comic books to date. There's a reason Alan Moore was happy to give his approval to For the Man Who Has Everything.
Shout out to Dwayne McDuffie too. Passed too soon.
Also my choice for best character. Watching him develop from enemy, to rival, to friend, to eventually mentoring and becoming a second dad to Gohan was great.
And yeah, it's a shame that he eventually becomes fairly irrelevant as the story goes on (like most of the non-saiyan fighters)
It's funny. When I was much younger, I disdained DB and preferred DBZ because it was more "serious" or something. Now I find DB, with it's focus on adventures over fights and relatively lower stakes, to be far more entertaining. It's also generally much funnier.
