I was so looking forward to this series after 6 seasons of the brilliant UK version. I was so disappointed that I only got through the first 2 episodes, I just couldn't watch any more. The humour is stifled (the show is quite heavily censored for language which seems so counter-intuitive), the host is not as acerbic as Greg Davies, the tasks are repeats of the original show's so no surprises, for the most part the contestants just aren't as funny or quick witted, and, even creator Alex Horne looks uncomfortable reprising his role as the Taskmaster's assistant. All in all, it's lost the edginess that the original series has.
I tried so hard to like this show but I'd be very surprised to hear that it's coming back for a second series.
*EDIT*
I want to add that had I not seen the UK version first, I might have rated this show higher. But in a way, this version just goes to show how good the UK version really is.
*EDIT2*
OK, so I sat through the whole thing and it did improve somewhat, necessitating a rating increase of 1 Star.
