Classic Supernatural was the golden age of the show for many fans. Others may prefer newer seasons. Both have amazing, kick ass qualities. But continuity can be an issue on any show that's aired for as long as SPN. Nobody likes retcon. 

We, the Supernatural fandom, feel that this can be solved by asking the current Supernatural writers to watch every episode of the entire series. We challenge everyone in the writers room to take the Supernatural Challenge. Watch every episode, in every season, in order. If we did, so can you.
