The film isn't bad, it's just not great either, IMO.
I get that Edwards wanted to ground this movie in reality and give the film a strong human element/story, but if you're going to do that, you need to make it compelling, I need to connect with the characters and their story arc, unfortunately Edwards didn't do this for me. It's been said before and I will reiterate it, Cranston is the only character in this film that had a story arc I was interested/invested in, plus the emotion he brought to the role was beautiful, this was sadly lacking in all if the other characters. They killed Cranston off way too early for my liking and that's when the film really went down hill for me. Johnson just didn't do it for me but neither did his story, so the blame doesn't solely lie with him. The reunion at the end for instance should have packed a real emotional punch, but it felt flat and somewhat cheesy.
The lack of Godzilla in his own film is a real problem for me as well. I loved the anticipation that Edwards created in holding back on the reveal of Godzilla, and the reveal itself was superb! But once you get past this stage, I want to see plenty of him for the remainder of the film. The fight scene at the end was great, and how I would of loved to have seen more of that! Setting up a great Godzilla moment, then cutting off to another irrelevant breaking news clip or military scene just p____d me off if I am being honest.
Finally, setting up Godzilla as the 'anti-hero' didn't sit well with me. It wasn't just the media that did this, the narrative of the film did this as well. When I think of Godzilla (54), he terrorised the people and city of Tokyo. The terror aspect in this movie was the M.U.T.O. not Godzilla.
Overall the special effects were some of the best I have seen and the final battle was EPIC! Unfortunately I was bored by the rest, and that was the majority of the film
