I once lived with a woman exactly like Jackie Tyler, only perhaps less empathetic. She wasn't a "chav" at all, but the defining feature of this woman was that she watched a minimum of five hours of soap operas every single day (and more on Sundays), and acted like that was where she got all her understanding of the world around her, like she'd walked right out the TV herself. That's really the only thing I'd hold against the Jackie character; that she's portrayed like an amalgam of every female soap opera character ever, and therefore doesn't have a great deal of originality as a character.
