I also just saw it and thought it was fantastic. The CGI scenes were all right, thought Godzilla looked kind of goofy but I think that's because they really wanted it to look like the original, and that was done incredibly well. The music that went along to him went along perfectly too.
What I really liked about the movie though is that a big part of it was a period piece. There was a huge effort to show what things would have been like right after the entire country got ravaged by WWII and how afterward the US was too busy worrying about the Soviets to care and the new Japanese government was too strained to do anything either. The main cast meeting because they had to sail a rickety wooden boat to go take care of all the mines left over by the war was perfect. Then Godzilla shows up and the characters that were set up perfectly come together to pretty much say, "These fuckers aren't going to help us, if we're not going to get killed by this giant monster we have to do it and on our own terms." Extremely based.
It's also nice to see a cast of characters who aren't Marvel quipping all the time and seem to genuinely give a shit about each other. The freshest breath of air I've had all year.
