I still continually watch the Pokemon anime but I cannot stand the main characters anymore. All of them just lost all meaning for me. Satoshi can go rot in hell, as well as most of his friends. Pikachuu is easily the worst thing ever as well. The only reason I continue to watch it is because of the Roketto-Dan trio.
Besides that, I wouldn't call Satoshi 'overused', just kinda bland and undeveloped.
