True, but with the caveat that actual "film critics" are an entirely different animal than "movie reviewers," who are generally held to a much lower standard, if at all. Granted, it's not like film critics don't sometimes cater to an audience either. Just look at Armond White, who manages to somehow interpret every movie that he doesn't like as being a secret exaltation of what he perceives as the moral degeneracy in Hollywood in the age of millennials, liberals and Obama (and often also manages to branch off into similar blathering about politics when discussing movies he does speak well of). The irony is that, when he doesn't go full hateboner for all things left, he's actually quite a skilled critic, but in order for a movie to have a shot at getting legitimate criticism from him instead of a vomited knee-jerk diatribe, a whole bunch of other factors have to align to his own views first, such as the politics of both the movie itself and everyone involved in making it, and his (seemingly completely random) list of film directors that he seems to actively either love or hate on a level that goes far beyond professionalism.It's a very different story with movies since all critics can see everything screened for the public no matter what their personal reputation is.
Most legitimate film critics though are members of critic societies, and that affords them some protection from the being blackballed by studios. Given how much sway review scores can have on the box office, that's a fair consideration. The real thing though is that film critics aren't as reliant on an income generated by ad revenue originating from film studios in order pay the bills (ad revenue yes, but not from the studio or distributor). Gave reviewers on the other hand generally must rely on the ad revenue they receive from the very entities whose games that they review, so objectivity is always going to be an open question. This is because the places online where gamers tend to congregate, and where studios ultimately focus their advertising efforts, are also the places where game reviews tend to originate, whereas marketing for movies tends to be far more generalized in where and how it appears.
