Just my observations....
Side looks great but the front is not as clean as the E46. The air dam in the lower lip looks hacked and the cutoff line beside the kidney grill is out of place. The grill should have been part of the hood like the E46. Maybe a facelifted version in a couple of years will smooth out the front.
Overall, still better than the new 5 and 6, IMO. It'll probably take me some time to get used to it but great designs shouldn't take time to settle in for acceptance.
