"Ghost" isn't very subtle, and similar themes have been done elsewhere with more depth, but I say just relax and enjoy. The best reason is of course, Whoopi Goldberg, who is hilarious and as always, very good. As for the story and the characters' reactions not being plausible, you really need to have a little imagination when you watch movies! I give any movie credit for not being bad, since there are so many dreary movies out there, and Ghost is not bad.
