I enjoyed it, but with regards to the human factor, my problem was that I wish they had just settled on one protagonist. I found the human element in this film to be completely unfocused, as it jumped from character to character not one of which had any big impact on the overall story, basically all the human characters seemed to be cruising along so there was no real tension there. Good excuse for some great scenes though.
Pretty awesome monster fights too, even though Godzilla kinda Man of Steel'd the first Muto. Good to see the real Godzilla back too, not that terrible Zilla guy.
I still prefer Pacific Rim though, it was just as silly but there was more kaiju fightin!
