Well put. This is exactly my feeling. Comics really train you to see everything as varying representation of an underlying reality, while people seem to have trouble seeing TV/movies the same way (probably because we're so used to photography being an accurate representation of "reality.")
AFAIK, if I can accept different actors playing the same roles, I can accept a different starship playing the same role as the original model, and so forth. Not a problem.
(Even so, I also have no problems if this movie does, in fact, break with continuity.)
