I think hot hatches make a lot of sense. They are good drivers cars that at the same time are practical for the family man or woman who has children or elderly parents to carry around. This way you can have fun with a practical car.
However if I wanted the ultimate drive, why get stuck with the compromises a hot hatch has to have, since it's based on an econobox? A proper sportscar could offer a better driver because it's designed on purpose to do so, unlike a hot hatch. In that aspect they are far less pointless.
