Time Out by Joshua Rothkopf

Is Joaquin Phoenix putting us on? After watching the terrifying, near-brilliant exposé I'm Still Here, in which the Oscar nominee's public and private unraveling becomes a sick joke, the question doesn't matter.

An artful piece of exploitation vérité.

Philadelphia Inquirer by Steven Rea

A meditation on a life lived in the public eye, I'm Still Here is strange, riveting, and occasionally appalling stuff, any way you look at it.

St. Louis Post-Dispatch by Joe Williams

Whether true or a hoax, I'm Still Here represents real risk-taking that I can only applaud.

There's a thrilling madness to Phoenix's Method.

Boxoffice Magazine by Pam Grady

I'm Still Here does leave us with one big question mark: What will Phoenix do next? How will he top such a flamboyant caper?

Chicago Sun-Times by Roger Ebert

A sad and painful documentary that serves little useful purpose other than to pound another nail into the coffin. Here is a gifted actor who apparently by his own decision has brought desolation upon his head.

Regardless of its veracity, this portrait of a drug-addled star who just wants to express himself artistically contains implications that exceed the filmmakers' intentions.

The A.V. Club by Tasha Robinson

If this is a documentary, it's a profoundly embarrassing one, in which Affleck has exposed Phoenix's soul and found it shallow and damaged. If it's a mockumentary, though, its greatest value is in pointing out the media's gullibility, and reminding audiences that even in an age of limited privacy, they still have to question what they're told and even what they witness themselves. It's cruel either way, but riveting nonetheless.

You've never been quite this close to a movie star, and after enduring the experience you'll likely never want to repeat it.
