I think if you take it as it is as a piece of nostalgic comedy then it's ok.
If you even attempt to compare it to the original then it crumbles badly
The show now is 3 million and 29 years away from what it used to be.
The biggest culprit for all this is the same way series 7-8 killed off the original run. Rob Grant leaving and Doug Naylor doing all the writing and directing on his own. It becomes a whole one sided view of what used to be a collaborative comedy.
For me the biggest criticism I have is that it's just not that funny any more. It's not bad, it's just not that good either. It's all very safe and by the numbers.
The biggest thing for me is that there is no overarching aim for the show. They are just a gang of misfits floating round in space going from one set piece to another. It's all boring
Anything critical I say means nothing for this Dave TV run as it is a ratings win for them as a channel. It's easily the highest rated show they have and easily the highest rating non-BBC, ITV, C4, C5 produced show. There will be more of it. It has that cult following built since 1988
