Generally speaking, the three of them either joined at the hip or working on their own never set out to make the best product they can make, but rather abuse every opportunity at making a movie or television series by turning the venture into an intensely personal favor they give to themselves. Combine this with their joint and individual typically common trait of never having their fingers on the pulse of what audiences want to see (and always could care less about it), and you have three entities who should not be in the professions that they are in, period.
Ronald D. Moore -
Technically, Ronald D. Moore may have been hired to produce and write a television series called "Battlestar Galactica" in 2003, but he clearly and transparently had other things on his mind when he took on the job. Doing a "Battlestar Galactica" television series was the farthest thing from his mind in 2003. Instead, he abused and misused the opportunity of continuing the "1978 Battlestar Galactica" series pop culture was clamoring for by instead, doing a version of "Star Trek: Voyager" that Paramount Pictures and Rick Berman wouldn't let him do. What showed up on the old Sci-Fi Channel in 2003 wasn't "Battlestar Galactica" but rather...."Star Trek: Psychoses." Sci-Fi Channel and Universal Studios being no lovers of the "1978 Battlestar Galactica" series said to Ronald D. Moore at the time...
"Groovy!! Let's do it!!"
"We'll try and pass it off as a 'Battlestar Galactica' series."
They got their reward with four unprecedented, low rated seasons on the old Sci-Fi Channel.
Of course, no one in the mass market domain wanted to see a dark, boring, and violent version of "Star Trek: Voyager"...but Ronald D. Moore and Sci-Fi Channel sure did.
Bryan Singer -
With so many projects on Bryan Singer's plate at any one time, he always gets remarkably little done. Right now, we have his verbal proclamation (in October 2011) of wanting to do a "Battlestar Galactica" feature film which we already know will never come to fruition because we all know Bryan Singer and how he lacks a fundamental work ethic, combined with Universal Studios life long desire of not wanting to do such a film despite their intentionally misleading, biennial announcements. We know he will indeed get "The Munsters" done because this is Universal Studios pet project (and excuse) for not wanting to do the "Galactica" feature film they announced in October 2011. So of course, Universal Studios will RAM "The Munsters" into the fast track of the production process. I predict "The Six Billion Dollar Man" will change producers and directors dozens of times before the project is abandoned. "X-Men 4", "X-Men 5", and the "X-Men Super Bowl 2013 Special with Lady GaGa" will probably all get done, but not by Bryan Singer.
Like Ronald D. Moore, Bryan Singer doesn't care about the directions pop culture winds are favoring but rather, makes the movies he makes (when he manages to make any at all) because it benefits and satisfies his personal tastes.
Universal Studios -
Universal Studios is the sworn arch enemy of whatever is popular in pop culture such as the "1978 Battlestar Galactica" series. Just read the archived http://www.scifi.com/galactica board from 1999 to 2005. Never will you see such corporate hatred unleashed upon the "1978 Battlestar Galactica" series, its fanbase, and anything remotely connected to both.
Universal Studios is without the doubt, the most pop-culture unfriendly Hollywood entity that has ever existed.
Without a doubt, the main reason why Universal Studios, Ronald D. Moore, and Bryan Singer will never achieve pop culture adulation, is because of the staggering lack of imagination and the staggering lack of inspired thinking among the three of them.
