There's a load of references in there, which they show over and over again; the starting point isn't smart, so repeating it incessantly isn't either. Phoenix is amazing, as are a lot of the other cast members, but they can't save a lazy, derivative, predictable screenplay from failing. Also, regarding the soundtrack, they could've used a lot of era-appropriate and psychologically fitting new wave or punk, but instead they keep on copying Bernard Herrmann (taxi driver, don'tcha know) and using the same two Sinatra songs repeatedly. And it takes waaaay too long, treating the audience like toddlers. Yeah, i get it already. 6/10, purely for the performances and cinematography. The rest of it sucks.
