Once you have covered the basics of the JW belief system and things the organization did in the past, there isn't much left. Honestly, you could get what you need by visiting JWFacts or any of a number of sites that have extensive information on JW beliefs and the WTS's past. A few hours of reading and you are up-to-date.
From then on, I could see the occasional short commentary when the organization puts out something new or makes changes or, I dunno... buys some liquor. Going through every video and meeting and convention and critiquing everything might keep a few people interested, but it's tough to imagine building a channel around it. To his credit, Evans was having some success with it, until he unmasked himself.
