I agree with sports animes. Other than that I add Sword Art Online, most harem animes (exception: Date A Live, that one is really cool), Kiss Note (didn´t expect anything to begin with but after one episode already ditched it xD)... bet there are a lot more that I have forgotten.
Pokemon, Yu-Gi-Oh and such may not be bad but I missed that hype back then and now I´m grown a bit too old to start watching those kind of animes^^
