Take a look at the videos in my signature - pre-Abrams Trek is riddled with HUGE game-breaking continuity errors. Voyager and TOS can't possibly co-exist in the same universe going by their treatment of warp speed, for example. The new movies fit in just fine as the writers intended (a branching continuity from 2233), IMO.
If Saavik and Zefram Cochrane can look completely different with nobody noticing, than the Enterprise can look sleeker too. It's all the same thing.
THIS !!!!
If you try to explain all the continuity problems and try to fit 700+ episodes and movies from five decades under one roof (sort of like Trek´s "Grand Unified Theory") you´ll probably end up not enjoying much of Trek anymore and start ranting at anything new that doesn´t "fit". My enjoyment of any series or movie is at its peak when I ignore these little bits and pieces of artistic license (and sometimes negligence) and take each as a separate entity - still as Star Trek, but more as a variation on the theme rather than a strict and accurate expansion of the Trek universe. To me this works with ENT, works with nuTrek ... but YMMV, of course

@King Daniel Into Darkness
I really enjoyed your videos, BTW
