I don’t think you act like that, but I don’t think it is a stretch to say that a fan of a director, musician, author etc may be more forgiving of a film’s flaws because they are a big fan of their previous work. I am speaking as a Weezer fan here.
Also definitely think are film criticism there is a lot of running #narratives that keep think pieces ticking over and Cuaron being a master of cinema who can excel in any genre is one of them.
