edit: originally this question asked specifically about modern comedians, and that's what I've tried to answer below.
The UK comedy scene, once called 'alternative comedy' started as an anti-Thatcher subculture in urban comedy clubs. 'Thatcher, eh?' used to be a lazy go-to line for a comedian to show he was 'one of us'.
Before that, UK comedy generally depended on super inoffensive 'mother in law jokes', or blatant racism at the other extreme. So be grateful!
By mil jokes, I mean jokes so bland (and usually unfunny) that you wouldn't mind telling them to your prudish mil, not jokes about her.
The above being said;
There was a great deal of police brutality, particularly by the Met.
There was little attempt to provide alternative employment in the old coal areas. Many miners have remained unemployed to this day.
The ex-mining areas, generally up north or in the other home nations, have remained economically depressed for the subsequent generations.
More broadly, Thatcher is the figurehead of the philosophies which degraded our public services, and fostered horrendous inequality.
