BrooklynKnight said:First they need to clean up the first 3 seasons with some valid explinations to fit them into the existing timeline before they can "reset" the show and start making it an actual prequal series.
I don't think cleanup is required. It'd be nice, but we can do without it. We fans have always gotten around inconsistencies in the past

However, the one thing they cannot afford to do is engage in lots of cleanup before trying to focus on being a prequel. Spending a bunch of episodes revising history is not apt to be interesting, and would not be good for a sagging viewer base. Instead, if they are going to clean up, they should do it in context of being a prequel. Slip the repairs into other storylines as they go.
