Everything about that movie works except for the characters. Had Cranston been kept around the entire film, I honestly think we'd be having a different conversation about it.
I like ATJ, I like Elizabeth Olsen, Sally Hawkins and David Stathairn and Ken Watanabe are all great actors. But man, the human characters were dull beyond all reason.
I get that Edwards wanted to take the Jurassic Park/Jaws approach with Godzilla, but it worked for those films because the characters/actors were likable. You don't have that, you're not getting away with it.
I have no doubt if Cranston wasn't killed off, at least at the beginning, 2014 Godzilla would have been a significantly better movie. I watched it about 6 months ago for the first time since 2014 and the movie completely flatlines when he's killed off. It's not that the film is terrible after that, but all the life that Cranston brought was completely sucked out of the movie.
