Here a a few storylines, or generic twists which I frankly dont want to see again.

"Thier my child"

Benidorm did it the most recently and Desperate Housewives and Will & Grace had a stab at it too. Is the classic storyline where 1 person thinks thier partner is having an affair, but it's turns out they been in contact with a love child.

"Thier not your your parents/ I am your father"

Eastenders, Desperate Housewive, Queer as Folk, Deep Space Nine, there are many shows or any genre that hasn't done this one...Be it a parent covering up after the death of the natural, a classic adpotion story, a reveal abduction, a sister that turns out to be thier mum or a mum that turned out to be possed by an alien who ensured you your born to filful your destiny. This one comes in many forms, but the revelatory stage is alwayspretty much the same...You weren't ever gonna top the Slater storyline in Eastenders, so this old tambourine should have been hit for the last time then.

"They've got a secret - oh they killed someone"

What show hasn't done this one? Someone either demented or troubled turns up or someone you becomes the former or the latter, and after painstaking wait, this old nugget resurfaces. The current culprit is Waterloo road, and whilst I'm sure the team will put it's own twist on this recycled turd, it's the one downside to the new series. Its not as if who dunnits have got dull, or the slow revelation format is dead an buried, it just that its pulled off far too predictably.

"The **** has issues"

I think Prisoner Cell block H takes the crown for this one and people have pitifully tried to emulate what was once very much unique to this show. Ok thats not all that true, but I fight with my dying beath PCBH made it something people really wanted to copy...Just like Willie in Ugly Betty or Multiple cahracters in any show made by Shed production...You have a true bastard, somene you love to hate, someone that appears to have no redeeming qualitites but then they crack that crust and all of a sudden you really feel sorry for them and for the rest of the show your stuck in in dilemma and wanting to hate them but feeling very sorry them. When done right it makes for great TV, But where as these other formats are a like a lasagne (many ways to make a good one.) This type of storyline is a PIMMS N0.1: If you dont get it exactly right you might as well have not bothered.

So theres a few, theres many more!
