I've always been intrigued by the artstyles of the witches, love me some fun monster design.
But wondering what the show is like. As I get older I find myself having less patience for certain types of anime bullshit (libertarianism, loli, that kind of cringe)
So, is Madoka worth watching or is it 
It is both worth watching and cringe.
To be serious I'd say it's not bad, but it's in my top 5 of all time so I'm obviously pretty biased. There's definitely some edginess but I wouldn't say it revels in it. As far as sexualization goes, their skirts are pretty short but imo that's about it and the magical girl outfits aren't really worse (see reference).
