Yo, over enthusiatic anti-captive hunting reviewers, there was NO WAY that anyone can watch this show and not be against stupid captive hunting. And that's exactly what Louis portrayed. He looked physically ill most of the show, and at no point did he not push people to explain why they would do such a cruel and useless thing.
Just because he didn't do a hard hitting documentary as you wish, doesn't make it a problem.
He wasn't trying to show facts and figures like you want, he just did a great job of showing the ignorance and insensitivity of the participants. When he asked some of them what their limits were, and they had NONE - that gets the point across pretty well.
Go watch it again, and try to figure out your allies better next time.
