I missed Terry Chen but saw Mike Dopud.
According to IMDb, Dopud wasn't in the film. I guess you just thought you saw him, like I thought I saw Teryl Rothery. (I know -- a Vancouver production without Mike Dopud? Inconceivable! But he wasn't there. Staggeringly, neither was Roger Cross.)
It really captured the spirit of the old movies,
Sort of a hybrid spirit, since it's combining the seriousness of the earlier and later movies (where Godzilla was usually a villain) with the heroic Godzilla of the later Showa era. But I guess maybe amalgamating elements from every era is a good way to relaunch the franchise.
I didn't like the cutaway from the action in Hawaii either, and I liked that Godzilla was portrayed as more of a helper to mankind.
I think they could've shown us a little more of the action, but I understand the value of only teasing us until the climax. The director was inspired partly by
Jaws, I gather (hence the family name Brody), and in that movie we didn't get a clear look at the shark until the climax (because the animatronics didn't work so well, but that turned out to be very much in the film's favor suspense-wise).
As for Godzilla, I think I prefer it when he's a villain, or at least a sympathetic antagonist. Even when we need him to save us, his relationship with humanity shouldn't be too friendly. He should never be a helper to mankind, which implies a submissive role -- he should be acting for his own ends, which sometimes conveniently align with ours, but heaven help us if we get in his way. He's a force of nature. We may be able to tap a volcano to power our homes, but the volcano will have no allegiance to us and won't hesitate to bury those same homes in lava.
I don't know if Mothra would be appropriate for a sequel since it feels like they covered that territory already with the MUTO.
Except that Mothra has never been the villain, except when under alien mind control. Mothra has always been portrayed as a benevolent or at least neutral deity, meaning no harm to us unless we get in her way as she pursues her goals.
Indeed, that would be the main problem with using Mothra in a sequel -- if Godzilla's the hero, Mothra has no role to play unless she teams with Godzilla against a worse threat, say, King Ghidorah or Battra.
