...and let's just say that about three minutes in, I got a big stupid grin on my face, and about 120-odd minutes later, it was still there.
On the whole, I thought it was spectacular — I caught it in IMAX 3D, and the image was gigantic, crystal clear, and smooth (though still film-like, unlike The Hobbit in 48 fps). One of the things I really appreciated about the movie was the level of world-building and the multiple narrative layers — the subplot about Newton and Gottlieb searching the Hong Kong underground for kaiju parts practically functions as a movie-within-the-movie, distinct in style and tone from the Jaeger storyline. (And Burn Gorman looks more or less how I imagine the fussy bachelor scholar-scientists in Lovecraft's fiction.)
If I had any real reservations about the movie, it's that I would have liked to have seen more Jaeger-kaiju action. And I was disappointed to see that Perlman never had any screen time with Elba. I'm sure I'll think of more issues later, but right now, I'm just savoring the imagery. I may actually see it again.
