Finally watched this while working out tonight. It wasn't that bad, overall. Affleck was certainly the low point. And making deflategate the focal point of that interview seemed idiotic. You are starting your new show and one of the main topics is something that has been beaten death for a year? Dumb. And in that vein, it was kind of the antithesis of John Oliver, which feels so present and resonant. Nothing was really interesting or informative or close to cutting edge.
Ok, maybe it was bad, but as someone said above, boring is probably a better description than bad.
But still, the reporting about the ratings is just as irrelevant. No one cares about live time-slot ratings, least of all HBO. That's not what they are looking for.
