If by "Aliens you mean "Committees" who have sucked the creativity out of making movies; then yes, you are rightI have a theory that Aliens take our best and brightest when they feel they have peeked and replace them with a copy, hence the copy is not as "sharp."
James Cameron- Obviously taken after Titanic. Then the copy made Dances with Blue Aliens that Sexually Assaults Animals.
George Lucas- Obviously taken after Last Crusade. Prequals, KOTCS. Need I say more.
Spielberg- Taken after Minority Report, escaped with rage after seeing his copy make KOTCS and then the original made Lincoln and then was taken again. Maybe the original made Bridge of Spies and The BFG, but he be gone after that.
J.J. Abrams-To my surprise his Star Trek was great. Then he was obviously taken and I think they made a really bad copy. Star Trek Into Darkness, new Star Wars, etc.
Okay just having some fun after being sick for nearly two months and finally better so no one get all offended, or do.
Those directors made New Levels of money for Big Studios.
Studio Execs on the receiving end of that money felt it important (...) to solidify their status as Power Players by allowing marketing departments and test screenings to have more pull in what got greenlit, what didn't, and what needed re-editing.
Add evolving distribution territories and the capacity the send a movie via internet (versus shipping 10 reels at 30 pounds each to as many theaters as possible) and we have a completely different industry. It's like Phone Booth manufacturers vs iPhone manufacturers.
