Me too but what changes did they make to the titans(kaijus)?
I don't know all the changes. The one that is most noticeable is Mothra. More colorful and more moth like in looks. They changed Mothra's sound too, its more a chirp type thing. The wings look really long too. I think there may have been a reason for all of that too. But without seeing the film, I don't know if my theory is true. LOL
All the other monsters look the same.
They might have made Rodan's horns on the top of his head a bit more sharp in looks. He seems more red and fiery than I remember too.
King Ghidora looks the same.
Godzilla is pretty big looking ... and it appears his back will light up with electricity or atomic type thing. I remember when 2014 film was out, there were complaints that Godzilla was "fat". And I don't mean phat .... I mean folks thought he was over weight. I find that hilarious. So ... on that note, no, he has not lost weight and looks just as big as he did in the earlier film.
Trying to find a good picture of Mothra, the attached is a poster but other art shows Mothra with yellow coloring along with blue..
