I read the review and found nothing disappointing really. Audi is just following it's own path. Sporty cars that make you feel confident , secure and in control at all times.
If someone wants to do powerslides and other childish stuff , clearly Audi is not the marque for him.

Furthermore i remember that times had said that 1 series was a very disappointing car and they weren't trilled at 3 series coupe either.
