@Kizuro yeah well in that case i can only say if you don't like it don't read it^^ as long as it continues there should be people who love it. also i know many anime/manga that definitly overdid it, and if i compare it then Sao has pretty much no romance xD also while it is there its rearly the main focus of the story, i didn't read the light novel so i can't say anything about that but what i saw in the anime is, at least in Asuna and Kiritos case not that far off from being normal ... or as close to normal as a anime can get XD. IF anyone overdoes it there then its Suguha XD or Sinon but for different reasons.
Still i'm surprised you didn't like it for that reason, many start disliking sao for the 2nd part of the 1st season
