Aw Matt, I'm disappointed you didn't like it. I'm going to disagree that this movie has much to do with Emmerich or Bay as Del Toro clearly has a lot more sympathy for property damage than those two. There wasn't really a moment where someone walks by another person getting obliterated without batting an eye. There's a real sense of the effects of these fights on this world and some sympathy for the plight of people living under these conditions. I thought the actions in this movie had genuine consequences, which really don't happen in Bay or Emmerich's films.
Also I disagree with you that this doesn't fit in visually with Del Toro's previous work. Sure, this is a big budget Hollywood movie but it's also the grungiest looking big budget Hollywood movie I've seen in ages. Instead of creating giant robots and a base that was design by Apple, we have robots that look like they've been used repeatedly and a base that has certainly seen better days. Del Toro has a real affinity for world building in his films and while I can agreed it's a little subdued in this film, it's still on display. I doubt any other director would have had an entire section of a city built out of the carcass of a dead monster let alone actually make a set of it. Also I am 90% certain that if Del Toro didn't have a hand in this script, there probably wouldn't have been a black market for Kaiju body parts which I think is a very Del Toro thing. Also this film clearly had a color palette and honest to god cinematography which I don't think I've ever seen in a Bay or Emmerich film. It's a subdued aesthetic but it's definitely a Del Toro aesthetic firmly on display in this movie.
Is this my favorite Del Toro movie? Not by a longshot. Still I think there's enough of him in this film that it elevates it past standard blockbuster fare.
