Here's my review of it..
It's hard to grade a movie like this because perspective means a lot. Viewed purely as a Godzilla movie, it sucks overall. Godzilla is barely in the movie, and he's not even really the main character. Instead the movie focuses on the incredibly uninteresting human characters. The main character, who Mike mentioned in the main character of Kick-ass, is about as interesting as a fruit fly. I've seen NPCs in Call of Duty games bring more sympathy out of me than this guy. Bryan Cranston's role is greatly exaggerated in the trailers, and he plays his part well, but, not to be a spoiler, there's a reason why he is credited as the last big actor in the ads. Still, Godzilla movies have never been known for their human characters, except for maybe Dr. Serizawa. The main character in this is almost painful to watch at times.. almost like the director told the character to suck.
It's too bad that American filmmakers still haven't realized that what makes Godzilla movies great is Godzilla. At times, Godzilla feels like part of the background. And this is sad, because when Godzilla is made the focus of the movie, the movie is f*cking awesome. The movement, choreography, and fighting of Godzilla is better than it's ever been. When he is left to shine, he sure as hell does. Sadly, these scenes are VERY VERY few. Honestly, this feels more like a disaster movie than it does a monster movie, which can be attributed to the other monsters in the film, which I didn't know even existed because I've been avoiding most trailers because I wanted to be surprised. When stuff is being destroyed and the monsters are running wild, the movie is at it's best. The human drama is not really worth investing in. I mean overall it hasn't been in nearly every Godzilla movie, but because they try so hard to make us care, it gets more annoying and glaring when we don't.
In conclusion, these complaints aren't enough to me not recommend the movie, but for us hardcore Godzilla fans, while this is a major improvement on the 1998 "Zilla", I'd rather watch one of the recent Toho movies. However, if they do make a sequel which I think they will because they leave it open for one and this movie will likely be very successful, if they can remove what was bad from this and expand on what was good, Godzilla 2 could be one of the best.
As far as a grade goes, as a Godzilla movie, a C-. As a disaster movie, a B+.
