As a fan of the kaiju genre. I'm so utterly sick and tired of hearing this complaint from people.
"We just want monster fights, no human characters"
So you want an entire movie of the screen time being just the monsters themselves. How would that cover 1 and a half to 2 hours?
Human characters aren't the problem.
****** or boring human characters are. G14 (Except Joe Brody and Serizawa), KotM (Except Serizawa) and Godzilla vs. Kong (At least the Godzilla side of the story) show this.
What made Kong: Skull Island work was the human characters being actually pretty decent, not Shawshank Redemption or Citizen Kane levels mind you but to the point they were worth a ****, characters you cared for or related to.
Another example of good human characters in kaiju films. The original Gojira, Heisei Gamera Trilogy and GMK: All-Monsters Attack.
What a giant monster just needs is good human characters to keep the plot going.
Shocking I know right to find out the truth?
Sorry, I just had to rant and vent this out.
Edit: Also factor in, hour and a half to two hours of just monsters let alone fighting, do you realize how much money they would have to spend on just the CGI alone?
