“Oscar phobic” doesn’t mean the movie is bad, more that it’s the opposite of Oscar bait.
The kind of movies that the Academy will just never recognize for acting awards - often these can be in the action, comedy, horror and sci-fi genres with a few notable exceptions.
IMO “The Death of Stalin” is a very good example of that. All of the actors are on the top of their game, but it’s a black, political comedy taking place in the Soviet Union, so exactly the opposite of what the Academy would even consider for an Oscar. In my personal view Simon Russell Beale as Beria is particular noteworthy: He is terrific, ie. absolutely terrifying in the role and I can’t imagine an actor playing the mass-murdering, pedophilic head of the KGB getting an Oscar (he got a BAFTA at least).
