I know what you mean about that. I felt that last week's episode seemed a little subdued and this week's even more so; Holly Walsh definitely appeared scripted - not unfunny, just not spontaneous. However, neither episode was particularly substandard, they just suffered by comparison.
The one thing that does light up this show for me is something that has been highlighted before, that everyone, guests, captains, host and audience alike, seems to be having a blast. Something that causes that much enjoyment among its participants is definitely okay by me.
