I think the new Enterprise looks fantastic in space.
Indeed; while I'm lukewarm about the reboot, it does have some dang majestic space scenes. My favorite is probably the scene where the Enterprise warps in and rescues the Jellyfish from the Narada's barrage of torpedoes; a true "Here comes the cavalry!" scene, made even more memorable by Giacchino's masterful score.
...and while I'm not sure how I feel about hiding the Enterprise underwater, the shot of it rising out of it was pretty goshdarn spectacular.
