Pfftt... You have just noticed that? Hollywood is filled with talentless hacks who only care about fan services pandering and shoving their politics down the average Joe and Jane's throat nonstop. To call them pretentious would be a understatement.
Doesn't every writter reflect their politics and beliefs in their writting?
Also I doubt the Power Rangers movie has any philosophy to share other than making money from shitty nostalgia.
There is one other philosophy there: There's a nostalgia filled sucker born every minute.
A lot of people are getting hyped for what appears to be a generic, run-of-the-mill 'edgy' reboot of a show from the 90s (that any half decent writer could think up and discard for how lazy such an approach would be) and those who are skeptical or critical are being decried as 'haters'.
