The British seem to love creating over the top characters and are obsessed with bodily functions and double entendres. I get the premise of the show and think that the concept is quite clever, people from Britain vacationing on the cheap, but the characters have been done to death on Brit shows, I have seen so many shows where they take the quirkiness way over the top and make the characters more of a pantomime than real. Some of the writing I must admit is very funny, and some characters one could not warm to, and in real life wouldn't have anything to do with. The characters that you think you would find hard to like turn out to be the most likeable because they don't take their actions over the edge. There are two characters in the show that I absolutely thought were the wrong choice, and their lines did not come off as funny nasty, but just plain nasty and horrible. I have watched a lot of British comedies in the past and have enjoyed them, but they are now becoming repetitive. I think if you are British you will relate to this type of comedy more.
