We lost a sweet, innocent, caring character, who was seeing the wonders of the space for the first time, replace by a cold, distant and overly-aggressive one, whose journey back to being human was far too easy (on but she has massive boobs, so that makes it all better).
Add to that all other characters were ignored and dumbed down in favour of Seven.
