Animation is good the first two movies are decent but nothing too impressive or revolutionary. Some phrases are actually good and deep but nothing really live changing.
The story at first is good but it has been done so many times that it isn't as effective as it once was. But the analogy toward religion is good.
Action scenes are cool the best is the fight of Godzilla vs the Vultures and the lost civilization is actually interesting but not explored, we don't receive any explanation on how they survived and over all the characters aren't that compelling. When Yuki died I was just relived since I found her annoying. Also Ghidorah is extremely weird I don't know whose idea it was to make him like that but it doesn't work, a fight with Godzilla would have been better.
