I know it would've made more of an impression on me if they'd used the original ship. I can't deny that. The original ship is the best looking. (This from a guy who got into Trek in the mid-90's) Sure, the hull should be metallic and way more detailed, in a way the original could only hint at. But I fail to see the logic of changing the shape. It's not like they did anything radical, but...why make such meaningless changes to the upper levels?
, I like the new ship (so far) just fine. It just seems that the changes they made to the sub-bridge area were...pointless. It clearly isn't in canon. Sorry, but there is no way I can believe that a ship would start out looking like the TMP version, then look like Pike's ship, then Kirk's, then end up looking...like TMP again. So this is pretty clearly a different universe where the technology is significantly different.
Here's hoping the movie is good enough that I don't feel the need to nit-pick...
