While working on TNG, Roddenberry was reportedly suffering from brain disorders, diabetes, high blood pressure, and depression, which ultimately culminated in a stroke in 1989 and his death in 1991. It's easy to see how his condition could have influenced his fanatical behavior while developing the series. For a man in rapidly declining health, it's not unusual to cling to an idea of a utopian future without lust, greed, or conflict after realizing he probably won't live long enough to see it happen for real. Still, by the end of the third season, Roddenberry's tyrannical grip on the scripts had purportedly caused 24 writers to quit the show out of frustration. Or maybe it had something to do with the unbearable stench caused by the new TNG uniforms, which apparently smelled worse than the inside of Shatner's girdle.
Everyone in this picture might as well be wearing a tiny red shirt on their nose.
It turns out that spandex is like the memory foam of smells, retaining the whiff of every drop of boob, armpit, and ball sweat you ooze into it. This slowly turned the TNG uniforms into skintight torture devices that steamed the actors in their own disgusting aromas throughout the day.
Also? They were apparently very painful. According to the show's costume designer, "Tight spandex fabric also gave the cast members recurrent back problems" until the costumes were thankfully replaced with wool alternatives around Season 3. However, that still leaves nearly 50 episodes of The Next Generation where the main cast was constantly in a state of nauseating olfactory agony.
Best Star Trek series ever.
