Nathan, Kelly, Curtis, Simon and Alisha. They should have kept them on the show! I loved this show but when they took them off I stopped watching. I don't see any good reason why they should of been changed, these fictional characters taught me a lot. Nathan taught me its okay to be myself and tell jokes and be funny, Kelly taught me that it's okay to have an attitude and stick up for myself, Curtis taught me that we have to sacrifice things for the people we love, Simon and Alisha showed me the greatest love story of all time. I used to stay up to all hours watching this show online and now I am bored all the time because I have nothing to watch that will be even half as good as this original show was.
