Everything from Paramount shortchanging the budget
Waitaminute. Trek 5 gained a higher budget than Trek 4 received. (although admittedly not that much higher) Still, how is that shortchanging? Did he really think he was going to be handed a vastly larger budget than Trek 4? Wasn't the reason why he chose a non-traditional effects house was because he knew how much money he was going to be handed in pre-production, and wanted to allocate more money elsewhere? And perhaps a noteworthy question: Why were Bennett, Nimoy, and Meyer able to create better films with
less money involved? My answer: because they were better filmmakers.
What I find with Shatner defenders is excuses. Studio wanting humor - which is fine, if you find a capable screenwriter who can write half-decent humor. Humor was an element in all of the films, and I have seen capable-to-good humor put in some fairly dark material. Budget problems with FX? Cut down the FX. Nimoy had to do it, I am sure that Meyer and Bennett had to as well. I have never made a film myself, but I do know someone who does, and one of the most rudimentary things that they tell me is that they make the best film given the parameters laid out for them. But they don't make excuses after the fact. Directors know that they are ultimately the ones who are going to be responsible for the success and failure of their movies, and certainly
planning is one element that provides success. I don't see Nimoy, Bennett, or Meyer making vast excuses for being given tiny budgets and all sorts of other hurdles thrown in front of them. I am sure that there are tons of politics and studio meddling that they have never ever shared publicly with Trek's 2,3,4 and 6. My guess is that the reason why they made successful films despite their shortcomings in terms of resources and interference is that they are/were adequate for the task. In other words, that they are/were decent-to-good filmmakers.
And to take this subject out the realm of Trek 5 for just one moment - one only has to look at the absolute
garbage that Shatner has directed elsewhere to come to the realization that he is just frankly a bad filmmaker. I don't think his ego will allow him to admit that to himself, so in his eyes the problem has to come from someone or somewhere else.
