Aren’t you already on Reddit? I’ve seen that opinion parroted 10,000,000 times while simultaneously praising the marvel films that are below Avatar in every conceivable way.
They’re all just simple popcorn flicks. Avatar just goes all out with the visuals, action choreography and the cinematography.
Marvel movies have similarly weak scripts but they also have horrendous visuals, weightless CGI and every scene must have 1,000 cuts.
