The show just keeps getting less and less funny for me. Like the drag race and shooting of the wine bottles in the recent episode. It just never goes anywhere. The first season (or series) was so great because Oz would go on and on about something tedious like fruit smells in the wine and James would get fed up, call him an ass, then go to a bar to have a beer. It was the fact James was working against Oz's success that made it work. Now they just look like a gay couple on "holiday".
I'm of the opposite opinion - I enjoyed the first season, but I am enjoying this one more. Especially now James knows a bit yet still likes to say daft things. It is the mix of wine drinking and odd other bits and pieces (along with the presenters) that make it great for me.
The voiceovers and script are funnier and sharper for me, this season, too.
