I'm making a video about Knight School

So this video is going to be on a 6-episode show called Knight School. Now what I'm think is that I make 1 big video about the show vs 6 videos focusing on one episode.

I think that's the better format for episodic stuff like this but i'm just worried that spending this much time on a video that might flop. However I would love to make longer videos like this over time. What do y'all think?
