Shows like Pokémon, Digimon, Beyblade, Yu-Gi-Oh and all their clones. I hate them because they're pretty much the only shows that are actually mainstream, and then everyone not a fan of anime watch them and conclude that all anime is crap.

I'm not a big fan of Dragonball Z either. Goku powers up for 5 episodes then spends the next 3 episodes punching the bad guy. Bad Guy and Goku then argue for the following 2 episodes. Bad guy then decides to jump into the pissing contest and powers up for the following 6 episodes, then beats the crap of Goku for then next 2 episodes. Next 3 episodes consist of Goku pretty much going all "Nya nya! Didn't hurt!" *gets up* *powers up for the next 10 episodes*". Meanwhile, Gohan and the little bald guy wish no nose whose name I'm forgetting spend all this time trying to find out what 2+2 equals to in order to solve the big boring puzzle to awaken whatever super good guy who will later go help Goku beat the crap out of the bad guy. Lather, rinse, repeat. >_<

That's pretty much what the shows looks like to me.
