That'll be the one word you hear more than any other in this series.
Chobits has likeable characters (Chii is adorable), amusing sexual innuendo, awesome artwork and all of this is bound together by a sensible, not to mention good, plot.
Maybe not for those who are into their action animes like Gundam Wing, but it certainly shouldn't be discounted as a ‘girly’ anime either. I highly recommend Chobits as an excellent light-hearted anime.
