I think the main dislike I have of the one piece anime series would have to be Usopp...All he does is yell, cry, and more often then not has a snot drip ....however I still love the show...its the same thing with sailor moon...I love the show but serena's endless whinning and racketous noise making can get tiresome...
Ok my friend I'm not sure whether or not these have already been suggested to you but if you are looking for some feel good animes that draw you back towards being younger I would Definitely have to suggest Sailor Moon its one of those classic animes that stays a favourite for all time, and on the other hand if you want an anime with a complex storyline and mind blowing ending then definitely go for the 26 episode anime Vampire Knight/Vampire Knight Guilty - again one of my all time favourites
Anime is actually one of my earliest childhood memories, I can remember waking up really early everyday and getting all ready for school just so that I would have enough time to sit down and watch Sailor Moon and the Sailor Scouts battle the evil people of the Negaverse with Tuxedo Mask - Who I sercretly had the biggest crush on...I've loved anime ever since
