I had a really great time with Godzilla.
I understand all the negative reception it's getting, and I even agree with them to a certain extent. But I guess people expected some kind of Pacific Rim movie, while Godzilla draws more from Jurassic Park or Jaws (mainly in terms of pacing). It's more a movie about powerless and helpless humans facing big scary monsters, than big scary monsters throwing aircraft carriers against each others.
But all in all, the important thing is that when Godzilla is on screen, he's glorious to the point of shouting and cheering in childlike wonder and joy.
