I never knew some fans hated Wesley before the internet. (There was even a usenet news group called alt.wesley.crusher.die.die.die) I didn’t know Whovians hated Adric either. Only one group of fans got their wish.
I remember back in the 80’s thinking he was a bit too clean cut and wishy-washy, but I never got to the point of hating The actor or character. At the same time, I also had problems with Riker and how clean marine and stiff he was. What I truly had the problem with was the writing of the show and the overused “Wesley saves the day” plot device. Could I be wrong in thinking that the character and actor took a lot of undeserved flack from fans due to the writing?
