There are a lot of plot holes in Supernatural, true.

Though I think we should be grateful that we got to SEE Demon-Dean and Human-Cas, instead of being forced to imagine it or demand the writers add these versions.

I do agree that some things were done quite badly in Supernatural, such as Death's demise? Reapers are angels? But overall, I think we shouldn't be too hard on the series. It takes a lot of effort to produce one episode.
