I think the main reason you have problems with Grey's (and MY biggest problem with the show) is that they're so dead set on the soulmates, love at first sight crap. I just can't get behind that kind of story, because it COMPLETELY takes away any kind of choice. GROSS.

Anyway, maybe that's the problem you're having? Becuase I can totally get behind what you're saying about Izzie and Denny. MAYBE they would have worked out if he lived, but we'll never really know. They didn't know each other well enough.
