I don't like the departure from the neck-attachment, or the unnecessarily pointed look of it. It would have been great as a starship on its own, but as an Enterprise, which had historically been ships of exploration, making it a ship specifically made to fight the Borg doesn't make sense. The worst part, I think, is that because of vehicle lineage "rules" future Enterprises will likely have to conform to this shape; for instance, the Star Trek Online Enterprise F, which is a dead ringer for a Sovereign class.
