On the other hand

a single glowing review from Pitchfork or Fantano could have an impact on a musician that a single film review can't (although even this is getting taken over by the importance of Spotify playlists). The film world doesn't have the presence of powerful taste makers; even Pitchfork's attempt to fill this void - The Dissolve - failed miserably. Part of this is structural. Positive album reviews can be tied to Spotify streams and YouTube videos; a lot of film hype occurs around festivals, and the average viewer may not see a film until a year or two after its premiere.
But largely you're correct - not only will you alienate your readers by being overly negative, you get cut out from advance copies of albums, interview opportunities, etc. At least the more prominent film critics are tied to powerful institutions - NYT, Time - which have too much clout to cut off entirely.
