Every character was terrible, pacing was atrocious. The soundtrack was forgettable and borderline bad. The fact they changed Godzilla's music is just unforgivable.
Visually it was good, IF and it's a big if, if you can ignore the random monster scaling. The monsters randomly grow to fit the scene. Need kong to fit on a boat no problem, he fits on a boat. Need him to stand toe to toe with godzilla and make buildings look small? Sure thing... hey we want to fight on to of an aircraft carrier ok! Also we want them to demolish 20 story buildings OK!
If I had paid to see this I'd be pissed.
