" A ghost I know " was a nice comedy, but not a great romance.

Well, actually the main romance wasn't that good. It was predictable and kind of boring. But the second couple was adorable. They had nice chemistry and they were funny overall. The two ghosts were pretty hillarious too. They were probably the best part of the drama, as they spiced up the plot and had nice dynamics with the leads. The performances were good too, especially from the secondary characters.

So, overall, six and a half out of ten.
