At least the title...a clever play on his earlier film Fahrenheit 9/11...was an interesting turn.
But the rest of it is a tawdry sequence of news clips taken out of context and interviews with loaded questions. And there was the now standard stunt cliche as Moore, in his usual slob attire, turns up at the Michigan state capitol to make a citizen's arrest of the governor.
The baseball cap is getting a little tired Mikey and you really should do something about the wrinkles and the weight you've added since your last film.
11/9 loses its way in the story of Flint Michigan's tainted water and West Virginia's teachers' strike. Nor is it strictly a Trump hatchet job. Moore makes a pretty messy attack on Barack Obama as well.
Moore strains credulity with his long comparison of Hitler and Trump and of the Reichstag fire and 9/11. Lip synching Trump's voice in an image of Hitler giving a speech --- and it was not very well done --- was a bit much even for Moore.
I'm no fan of Trump but I also am no fan of sleazy journalism and Moore excels at that.
But they have smeared an otherwise excellent film with excessive use of the "f-word" Over and over as a noun, an adjective, a verb, a modifier, an exclamation. Here and there? Okay!. In almost every line of dialogue? Objectionable! And although youngsters might enjoy it, they should not be exposed to this torrent of profanity. I doubt if there is as much foul language on a warship as there is in this film.
Although it's an apocalypse story, it assumes that in the face of cataclysm, everybody turns into a self centered, villainous bad guy. If something like this did indeed happen, there would be lots of good guys too.
It's also puzzling why two of the main characters vanish in mid plot for no discernable dramatic reason.
As for the ending (or lack of it), it failed to produce the dramatic impact that I'm sure was intended.
I would have given it an 8 were it not for the pointless bad language.
