I've seen all 13 episodes, but had not been exposed to the foreign versions.
My overall verdict: it's.... okay. It's not a horrible way to spend a half hour, but it doesn't really grab me as much as I would like.
My biggest problem with it is that it's edited within an inch of its life, and it feels so rushed that I'm very conscious that a lot is missing. That's a big difference between this show and Whose Line - they're both heavily edited, but on Whose Line I never feel as if I'm missing anything.
On Would I Lie to You, the first round has the four guest panelists telling a story, but because of time and commercial limitations they usually only fit in three of the stories. (Sometimes excerpts of the fourth story are shown during the closing credits.) This week Krysta Rodriguez's story was cut, and as a result she barely registered as a presence.
And then at the end of the first act Aasif says "Sabrina's team is in the lead" and I think "Well, of course they are, we only saw 3 of the 4 stories." (And what are they leading by? 3 to 1? 4 to 0?)
I agree with your comments about Richard Kind, Michael Ian Black and Allie Wentworth. All excellent panelists.
And I do like their use of New York stage actors like Dylan Baker, Becky Ann Baker, Laura Benanti and Nikki M. James - it reminds me of how Goodson-Todman used stage actors so extensively on their New York panel shows.
