From NetFlix:

James Franco steps into the shoes of famed Beat poet Allen Ginsberg in this star-studded biopic centered around Ginsberg’s poem “Howl” — and the widely publicized obscenity trial that followed its publication in 1957. Documentarians Rob Epstein and Jeffrey Friedman (The Times of Harvey Milk) direct, with an A-list ensemble cast that includes Jon Hamm, David Strathairn, Jeff Daniels and Mary-Louise Parker.

“Howl” is probably not for everyone (but what film is ?). Indeed it contains many words conventionally considered vulgar. That, in fact, is what the film is about: a courtroom trying to decide if the publisher of Howl (Ferlinghetti) must go to jail on obscenity charges.

So what is there to like about this “documentary” ?

• No dialogs are invented. Every single word that you hear came from someone in the past.
• Much of the original poem “Howl” is recited by the actor portraying Ginsberg. This is done is two ways: Either the actor is shown reciting his poem in a coffee house, or you hear the lines while watching very imaginative and appropriate animation.
• You get to hear pro and con courtroom discussions about Ginsberg’s work.
• You can see photos and film clips of the past and even see Ginsberg himself doing a small bit of recitation.
• Don’t miss the final screen notes (just before the credits) that tell us what happened to the personalities (Ginsberg, Cassady, Kerouac, Orlovsky, etc).

Of course the film was slanted in favor of Ginsberg: you wouldn’t make such a film if you objected to his work. But I was annoyed at coffee house scenes in which the audience acts in a way to make it clear they are “moved”. It just seemed phony.
