The 1st episode is a bit hard to handle because it's so different...but i tell you the characters grow on you very quickly. By half-way through the series (it's on DVD) you are hooked in the same way as The Office. Season 2 has been shown in the UK and should be out on DVD soon.
One of the funniest, but perhaps sickest parts, is the lad who fancies his mate's Gran. Having already seen him perform a rather extended Heimlich maneouvre I dread to think what will happen by episode 6.
That has to be one of my favourite sketches from the whole series. Some of the characters are over-played by the end - especially the 'only gay in the village' one - but the others stand up well. Series 2 has some new characters.
