everything in the last battle was pretty difficult to follow, not clear which monster is which necessarily. like the pterodactyl type monster that appeared at the end, is that Rodan? or is it another one. I cant tell.
cheaping out on animation costs by making everything pitch black does not help it.
Also that battle was pretty boring so it may just be me not paying attention, but i didnt fall asleep so think it's more the films fault for not engaging me.
