Since I stopped watching Supernatural around season 10 or 11, I am not sure why I tried this one. It is so similar and yet so different from the Supernatural story.
Originally John did not know anything about Mary being a hunter or of demons in general until she died to protect Sam.
Here, in this 'alternate universe', he was raised without knowledge of the supernatural but his father was a man of letters and he joins Mary in her quest to find her own father.
The only common thread is Dean narrating, apparently seeking something similar, so eventually we should get answers.
I do not know, I do not find it as 'funny' as I originally found season 1 of Supernatural but it seems they are trying for the same kind of humour rather than intense drama that came after. I will keep watching for a little while~
