I was never a huge fan of Susan. It wasn't the acting or even the character, I just think she was at time written dreadfully and in the end I was tired of her always being captured or running into things head first (not literally, obviously
).
I do however, really, really want to see her again in the new series. Or at least some actual undesputed mention of her. She is very important to the early history of the show and I think it would be nice to introduce her to newer viewers and give a nod to older fans
