No but which TV shows took a sudden turn to become very different from what they were when they started?
This is inspired by the execrable Disney cartoon my daughter watches called Sofia the First, which is all about a girl who becomes a princess and has to adapt to royal life. Then a few series in they obviously get bored of stories about her life in a royal school and shit, so they just say fuck it and invent a magical library so she can go on madcap adventures each week. I’ve seen so much of it and I hate it.
not a huge change but series 4 of The Thick of It kinda takes on the format of serialised drama (except it’s comedy) which felt like a bit of a shift. i guess the specials and the last few episodes of series 3 dabbled in the same thing but when you compare it to the slow pace of the early episodes it feels quite different
Parks and Recreation season 1 had Leslie Knope as a rather incompetent character with shades of David Brent and lots of Office-style cringe humour, they ditched that and had her as super capable going forward.
