What a lousy fucking critic, imo. You can't critique just individual components of a work. You engage with the work as a whole.
This argument only applies if you like the movie in question. If you dislike it, each separate element may "ruin" an otherwise acceptable movie.
Scarjo as Major? Ruined.
Batfleck is more violent and conflicted than traditional Batman? Ruined.
Superman is imperfect? Ruined
Alien: Covenant tries to give a new, allegorical spin to the franchise? Ruined
Brock and Misty are replaced in the new Pokemon movie? Ruined.
It's the worst with anime or comic book culture.
