Just started watching this now (on youtube. Sorry! It's all I can afford, gents). It's very well done, and manages to be amusing and rather passionate without being so slanted as to be worthless (though there is a slant, I get the impression the 'starting with a conclusion' thing is just for show - they are showmen, after all) . That circumcision one was even more horrible than I'd expected. Americans are kerrazy.
And is it just me, or was it blatantly obvious that the couple arguing about whether or not to circumcise their son would end up doing it because the man was totally whipped? She had no coherent arguments at all, while he simply failed to follow his experiences to any kind of conclusion, and neither of them appeared to actually bother researching or discussing the subject, and instead just whined at each other about how hard it was.
