Now we realize that Sam has his own love interest? Don't the writers see how seriously messed up this is? If your show has been going a certain way and everyone ones enjoying it, why would you think going in an opposite direction would work?!
There were so many possible developments for other characters. Now they have this weird Sam/Jim thing. We may be open to the whole seeing ghosts idea, but not many are open to ghost entering into other people's bodies.
Even though Jim is there, he's not there. It like worse than having him leave the show and staying on.
