Actually I don't agree with you, Gina, I think it's great stuff - the only thing I'm wondering is how they're finally going to resolve it. In shows like Neighbours psychotic episodes either get quickly forgotten or result in the death of the person involved, Corrie have been very careful to build David's problems slowly. However, he's going to need serious medical intervention at some time, it won't simply go away by itself.
I do hope they don't decide to have him turn 18 and suddenly be a fine upstanding citizen ... cos it doesn't happen like that!
