FilmApe’s review published on Letterboxd:
A genuinely hilarious film that makes the backlash surrounding Joaquin Phoenix's public appearances in 2008 and 2009 seem absolutely ridiculous. People seemed to be generally offended at the time by the fact that Phoenix was putting on an act, which I find very strange. The creation of I'm Still Here is really a harmless prank, so being offended by it seems to be a waste of energy. Embracing the film's complete commitment to lampooning celebrity culture is the way to go, and it is with that attitude that I have watched and rewatched the film.
