That Hitler example doesn't fit 100% because Hitler's sins are directly tied to his ideologies, Max Landis is just a creep.
Also, this is heavily downplaying what Landis has been accused of to bolster your argument. I don't think you're interested in an actual discussion and are rather just angry and annoyed over something you shouldn't be angry and annoyed about.
Please, dont give me this condescending bollocks, i don't claim to be right, but if i didn't want a discussion, i wouldn't be posting.
And i assure you i'm not angry, i couldn't stand Max Landis well before any of the MeToo stuff came out, and i think all of his stuff (that've seen) is dog shit.
My issue is with the idea of treating a piece of work like radioactive material, based solely on the name attached, i do find that ridiculous.
I actually wholly agree with the idea that art and artist are entangled, but it doesn't mean a linear connection (as in: a bad person only creates harmful art), or that "death of the author" has no merit.
Reassuring people that any trace of Landis is erased is silly because nobody had seen the movie yet, so there was no way for the public to tell whether the movie was making absurd political statements in the first place.
I think this is a corrosive way of looking at things, and fosters a simplistic mentality of aprioristically judging things outside of their own merits, which i find dogmatic, but more importantly a way to delegate away critical thinking.
In other words, if Carl Sagan had written Mein Kampf, it wouldn't have been any more or less psychotic and viceversa.
Although it'd be reasonable to say "we've rewritten most of the script because it wasn't good" (as it happens with most movies anyway), i find it toxic and wrong to foster the simple minded apporach of "we've rewritten most of the script, because it was written by a bad person".
Not because of what "damage" it may do to Landis (again, couldn't care less), but because of what it says about our approach to art, and critical thinking.
EDIT: To be more clear, the issue isn't the rewrite, it's the message telling people "the evil is defeated" because it gives the wrong message, as explained above.
