Perhaps my expectations were low, but I enjoyed it more than I anticipated, amd was on the whole pleasantly surprised by the production values. But I agree that immunity idol was NOT IT.
I'm guessing the commentary, which did feel a bit excessive, was because a huge chunk of the audience won't have watched any of the international versions, or the UK from a generation ago.
I'm not getting a huge amount of drama potential in terms of the contestants yet, but early days. I hope we get a bit more strategy and double crossing, and not people sticking to alliances and 'integrity'.
