The monster made less sense with Dr. Manhattans power
No it didn't. Not at all.
In the comic like the movie, Dr. Manhattan is beholden to fate or destiny or universal constants. He knows the future and can't change it. That is his limitation. Which is why he didn't save JFK or MLK or RFK or anybody else that died. The fans know this, doesn't matter if the President or anybody else doesn't know that within the world.
The alien monster invades Earth, teleports to Times Square and immediately explodes (cuz that's how it was constructed) killing thousands (maybe hundreds of thousands). This happens while he's attacking and trying to stop Ozymandias. He holds off Manhattan until it's too late which where he then reveals to everybody he's not some idiot villain explaining his plan before doing it.
Dr. Manhattan's story arc in watchmen could've been a movie in itself and makes all the more sense that he got fed up and went off in to the starts to try his hand at creating life. Not some compromised change where he's framed for the attack and pretends he has to leave Earth because he's seen as a threat. That outcome actually diminishes Ozymandias future plans since he came up with everything on his own and doesn't make sense if you consider Dr. Manhattan's powers.
, it being a nuke-like destruction coming from Dr. Manhattan made it more believable to be his fault.
This is apologist talk for the bull **** change.
It's not like the movie was set in the 2000s. The movie was set in the 80s with Nixon on his 3rd or 4th term.
To some, that made much more sense. A squid monster will look real out of place and random appearing out of nowhere in the end.
It's like you don't understand the whole point of Ozymandias plan at all.
It was all about an unpredictable threat that would force mankind to unite, something even Dr. Manhattan couldn't stop (which he actually couldn't stop from happening) and in that world outside of him an alien invade was the most terrifying thing possible the best creative writers could come up with (and it technically still is one of humanity's biggest fears in real life).
The only reason it wouldn't make sense for an alien to appear, threaten invasion, and then kill a bunch of ppl in the world's most known city is cuz the screenwriter and director could not properly execute that in the story. That's their failing not the story's.
Making movies out of Moore's work is literally the same as trying to make movies out of Hemingway's work. It disrespects the art form because the author put their soul into the medium the original story was told in.
Moore's style of graphic novel storytelling doesn't work on film.
Hemingway's bare, dry, iceberg writing style cannot be conveyed through film either.
These are limitations brought on by the medium and not necessarily the skill of the filmmakers
Eh. I'm not gonna sit here and pretend it isn't hard but it's not like every single Moore work, specifically his more independent work is in-adaptable to film.
V for Vendetta was great given what the source material is.
