Having now watched substantial portions of all 22 of those performance recordings, I can confirm this is the case.
Had I seen them live, there was one I would have walked out on almost immediately, about a third I would have walked out on at intermission, about a third I would have sat through mainly out of curiousity rather than enjoyment, and slightly less than a third I would have enjoyed but not enough to go out of my way to see work by the same artist again, but ONE (well two but both by the same artist) I enjoyed so much that I'll go out of my way to see its company live if they ever come to Seattle again.
Finding that one company was a perfectly reasonable time investment thanks to the ability to sample the full-length performances online, but absolutely would not have been otherwise.
For anyone curious, this company was NYC's "Temporary Distortion," which coherently combines theatre, film, and sculpture. See http://temporarydistortion.com
