I'm 48, will be 49 in less than two months. My kids, well my older two are moved out and on their own; Eddie at 13 doesn't watch a lot of television and when he does it's often stuff geared towards people older than his age group. Raymond, for a long time lived Pokemon (ugh!) and then Naratu, but lately not much TV either.
Okay, then I'll confess too... 46, 47 in the same "less than two months". Pokemon, ugh. Naruto, ugh (fans of the show are known as "Narutards"... ESPECIALLY if they run with their arms trailing out behind them at an angle - this was an "in joke" of sorts in the show, because this was how people wearing kimono had to run to avoid being blinded by their own sleeves - of course, the Naruto characters don't wear kimono, but they still run in this silly fashion). Funny thing is, one of the worst, Dragonball, was actually very cute and funny in the original first season. But most of that first season was cut from the U.S. release because potty humor in Japan is on a whole other level compared to the U.S., and it might have caused a national scandal.
UY was really what got me hooked on Anime, though I guess I'll have to admit I watched Speed Racer and some others when I was younger, but YU was really strange enough to really catch my interest and hold it. It's a silly anime, but at the same time imaginative. The characters are fun if not realistic.
I'll go out on a limb and recommend Jungle Wa Itsumo Hale Nochi Guu, which is silly and imaginative and strange and unpredictable in the same way that the original UY was. I know people who watched it all the way through, sat back, and said: "What the hell was that?!".
