Except Joel Hodgson and Shout! Factory aren't Hollywood fat cats. Shout! has been very good to the show, working to make most of the episodes available for purchase, and they are now re-releasing the Rhino-era episodes which have been out of print for some time. Having secured the intellectual property from Jim Mallon, they are willing to give Joel the kind of control that made MST3K the best TV ever in the first place.
And Joel... we're still talking about the guy who started the whole franchise with a skeleton crew on a no-name UHF station with almost zero budget. Even if the new episodes aren't as good as the old ones, I sincerely believe that Joel and the new cast, writers and producers will give it their all.
I also don't see it as any kind of slam against the new project that Mike, Bill and Kevin have chosen not to be involved. Mike and Kevin were involved with the original show for about 10 years each, and Bill for about 3 years. They made wonderful contributions, but they have their own gig now. They have a good thing going with Rifftrax, which itself has been going for the better part of 10 years, and works from a significantly different business model that must be pretty successful given the amount of material they are able to produce. Rifftrax has clearly declared its alliance with the new MST3K and will be selling the new episodes, along with the old episodes it's already selling. Plus, Mary Jo and Bridget are now riffing for Rifftrax in their own unique style.
It's a big enough world for more than one franchise making fun of bad movies. Who knows... maybe ICWXP will hit it big next!
