Last night's TV The Amy Winehouse Story on Channel 4 was a symbolic reworking of Jacques Peretti's 2008 documentary 'Amy Winehouse: What Really Happened'. It felt like pretty cheap television, just one new scene tacked on to demonstrate some semblance of contemporaneousness.   The original piece was a real ratings winner, gathering almost 2m viewers when it first aired - and at least that again on the 4OD service - reflecting just how compulsive the Winehouse story was. Last night's butchery with a punchline didn't teach us anything new. For it to go out two days after her death, on the day of her funeral, and before we've even established the cause of death seems a crass and whorey exercise in the TV equivalent of linkbating - what magazines and websites were getting colossal stick for on Monday.   Let's let her rest awhile before we can have a real look, with a real programme on what really happened last week. Not what really happened ... when you spend 48 hours in an editing studio hacking up a decent piece of work for the sake of dirty ratings.
