"Intriguing" might be the best word to describe this unusual film. There are problems including the fact that Geoffrey Rush does not shine throughout but there are enough highlights to ensure you will mostly enjoy this film.
I wouldn't rush to it but put it on your MIFF calendar as one worth considering.
And I would probably see it twice. The second time with hindsight, after knowing the ending, to read more into the minor characters and the guarded dialogue which in fact says it all.
There are sessions for this movie at the Melbourne International Film Festival on 31st of July and the 2nd of August. For tickets click here.
