I feel like the writers didn't know how to end the show
First of all, didn't Nick save Spellman's body? I mean what was that part with warming it up about? It came out of left field for me that they then proceeded to have a funeral for both Spellman and Morningstar. I thought for sure they'd find some way to transfer the original Sabrina's soul into her original body.
Her being together forever with Nick in the afterlife frankly does nothing for me. [shrug]
Instead it really ends up being like, "I watched four seasons for THIS?!"
Oh well. ๐
