I read an article on Suri and basically it said that alot of people secretly hoped that she would be an "ugly" baby (not possible, IMO), and then when she was born being absolutely gorgeous, people were put off about it. Of course, it was just an entertainment blog/magazine.....it was interesting, though....may be not totally off base.
Personally, I don't think ANY baby is UGLY. Some may look a little "different", but the pure sweetness and innocence of babies totally compensates for anyones preconceived notion of beauty, IMO. But I DO think that Suri is really beautiful, above and beyond the average cuteness of most.
