I'd never heard of this sitcom until I read glowing reports on BCG of series 2 and series 3.
I've just had a look at Series 1 Episode 1 but I only lasted ten minutes.
Visually, it's wonderful and the cast could hardly be better.
The snag, however, is that the script seems very "Red Nose Day" inasmuch that I wouldn't be surprised if it had been written on the back of a beer mat while the writers enjoyed a few pints over a single lunchtime.
As a one-off special for Comic Relief, it would be okay given that it's all for charity and everybody's just having a bit of a laugh. Under any other circumstances, it's just not funny enough despite the cast trying ever so hard to make it appear so.
There are plenty of jokes and some of them aren't bad but, on the whole, it's basically kids TV.
