I cannot think of any film that would have been better on opening night, as opposed to later in the run. In fact, since I've a touch of clautrophobia myself (no one is alone, esteemed BK), seeing a film later in the run would be more comfortable for me. And having the creators of a film watching me watch their creation, and knowing they were watching me watch their creation, would prove a terrible distraction.
Der B and I had something similar happen to us at a Red Lobster restaurant, when a group of executives from the company sat at the table next to ours. Our server was, understandably, nervous, which threw her work off balance, which was unnecessarily unpleasant. And having someone stare as I lifted my fork to my mouth was quite frankly disgusting. Not just bleh, but double bleh. Critics and others who opinions matter should be invisible, in my opinion.
