This is almost completely nonsensical. Shatner may have been the director (and he directed the hell out of the movie; it's gorgeous), but Bennett and Winter could and should have realized, for example, that Associates & Ferren didn't have the skills or the resources to pull off the effects -- that kind of due diligence falls upon the producers' shoulders. Beyond that, Bennett, by his own admission, was burned out on Trek after he continuously fought with Nimoy during production and post-production of The Voyage Home, and he didn't really want to be part of another movie. That, combined with a ludicrously rushed production schedule, is a recipe for disaster.
