Mostly people that agree the election was stolen will agree with the conclusions of the movie and those that do not- will mostly not watch it. You won't get a mass movement of the citizens to go after these people. For that to happen you need the media to join and..LOL...that won't happen.
If there is no action by law enforcement nothing will come of this. I don't see where the will is going to come from (most get their instructions from above)
Oh, I agree with you that there are many in the middle ( moslty "classic liberals") that have moved the right direction. I guess I was one of them myself until 6 years ago. They will call out the extreme left , maybe be more reasonable on taxes and CRT and pronouns but I still don't think that most of them moved enough to de-certify the election. I hope you are correct.
