I don't know. The shape I guess. It just grates on me. I mean, the look totally makes sense and is clearly intentional, but I think of the Enterprise, in all it's incarnations (except maybe the C) as an elegant thing of beauty, whereas this ship is more of a workhorse. It clearly isn't meant to be as pretty, but the juxtaposition of the similar elements with the less elegant design just doesn't do it for me. That being said, it is an excellent design
