You do understand that is entirely irrelevant to the question of whether $190k then was, or was not, significantly different from 1m today, right?
You also understand that "making the film", specifically the part that got less expensive, is a tiny, tiny part of the undertaking, right?
You also understand that without dedicated props departments (such as those at DesiLu), props take much more time and energy and are less efficiently made in this case as compared to TOS, right?
You also understand that the number of dollars put out for anything from a bit of particle board to the plastic for a switch and the material for the costumes has increased proportionally as well, right?
You also understand that as these people are not professionals, they are no doubt at all putting in more work on some things than the crew at DesiLu, right?
I am sure your understanding is wide and deep, O Anonymous One.
