I don’t like it either, especially if it’s excessive, but I don’t really care. Depends on the anime, I think. Take High School of the Dead, for example. If there’s too much ecchi and too little history, I drop it. But there was also a lot of action in this anime, and a lot of drama that made me forgive and forget all the ecchi in it. So, I don’t think it spoils the anime, because it has a category that everyone likes. If you like it, watch it, if you don’t, don’t. There are many animes that don’t contain it.
