only thing i didn't like was the framing of dr manhattan for the destruction of major cities. the whole plot of uniting humanty by using an outside force (giant alien vag monster) to end ww3 was one of the points of the original story. my bug is that doc manhattan was american and to frame him as the enemy of humanity doesn't present the level playingfield /clean slate that ozy was presenting the world. being that doc manhattan was american would only serve to unite the rest of the world against the US and blame them for the destruction. ozy was literally trying to change the human dynamic, but the movie ending would only serve to perpetuate the status quo in favor of one side over the other. i hope this makes sense, it's harder to type it out than think it.
aside from that, the rest of the movie cinematically, musically, theatrically was F'n beautiful.
