It isn't so bad. Not really attractive, but I wouldn't say it's ugly. I remember reading somewhere that the designers at Porsche wanted to make it look more like a 4-door 911 (see: 989 concept), but the owner of Porsche shot that down, saying that it needed to be able to comfortably sit adults in the backseat. And that's why we have that ugly, SUV-like rear pillar and hatch.
Edit: Concept images...much better, no? I wish they had chosen one of these designs, but it's not like I could afford one anyway.
