Question that has nothing to do with the actual film
Does anyone think that Bogdanovich's reputation as an insufferable letch has hurt the film's legacy?
No, it hasn't. Even though he is a terrible narcissist and a complete bore, this film (as well as Paper Moon and a couple of others) is still highly regarded.
Plus, Hollywood is really not that mad at him. Hollywood is not very judgmental about people like Peter. Judgment is for people in flyover country.
