I place the blame on it solely on Baird himself. I mean,..someone who NEVER watched Trek in his life and only directed two films in his life...
Star Trek II was Nicholas Meyer's second film and he'd never watched Star Trek.
Leonard Nimoy and Jonathan Frakes were first time theatrical directors when they made their movies, though of course they had some knowledge of the universe.
J.J. Abrams was not really a Trek fan and the 2009 film was only his second theatrical feature.
Stuart Baird is an Oscar-nominated industry veteran. He knows how to make a movie and tell a story effectively. His editing on genre films like Superman - The Movie and Casino Royale is electric. The script for Nemesis is a nonsensical mess and while the director should have had some input in it to improve it, those knowledgable in Trek lore (no pun intended) should have stepped in even more.
