I lasted 1:17 in. I enjoyed Edward's explanation of some of the ideas that I didn't listen to enough of to get to sound interesting. I'm with the others on their feedback. From the get go it's just a bit jumbled and doesn't really pull you in or give you much of a clue as to what the programme is going to be like.
I don't think it's an inherently flawed concept for a show. Improvisation can be good and funny, but it's got to have something supporting it or tethering it to something interesting or that the audience will care about. I couldn't identify that aspect of it in yours. I might be biased in that I do tend to like things that are more scripted. Even things like As Yet Untitled or Baddiel and Skinner Unplanned I think are done in such a way that while it may be largely improvised, the comedians will have usually put in the work of coming up with some kind of scripted ideas that they think might fit into the show however it may turn out. Or something like that. And even though an all-improvised show will fluctuate in structure, I think it should still have an identifiable beginning middle and end that make sense and flow well in some sense. Didn't get to the middle or end, but the beginning didn't do it for me.
I think there's definitely something to that Peter Cook quotation beaky posted about needing to know how to write before you can get to ad lib.
Thanks for sharing your videos. Good luck with future ones.
