Huw Edwards definately adds gravitas to it. I do feel it's on a bit late (10.25 on a sunday) and directly clashes with Match of the Day 2, which is a popular programme, so it might lose popularity because of that?
It was okay though..to be honest, I probably expected something a bit livelier, but then thats the sunday night problem..who wants to get into a raging debate on a sunday night!?
I agree the timing seems a little odd. Is it a live broadcast? Maybe Huw's schedule is part of it, and a desire not to clash with Newsnight on other days. I guess maybe a week day is seen as odd for a once a week news programme, where as sunday (like sunday papers) is a more natural time to reflect upon what's happened in the week until now.
