Why are classic 4 door sedans "disliked"?

I can say that the younger generation are turning to the 4 door cars. My son Ian (16) has several at the moment and one of them he bought for 2 breakfast tacos. That being said everyone has their opinions. As I still have a family to cart around both 4 and 2 doors have their uses and can be built to be bad to the bone as well.
