Babyteeth (15) lulls you into its emotional core, though its more conventional than you might expect.

It’s a teen cancer movie, though initially it looks like it is open to exploring other options. The first half resembles some kind of Mike Leigh style tragi-comic exploration of relationships in a Sydney suburb coated with a kind of American Beauty cynicism and sheen. But the kid is dying and that’s always going to take precedence.

Milla (Scanlen) is the one doing the chemotherapy but everybody in her household is having a tough time with their medication. Bogan boyfriend Moses (Wallace) is a drug addict while her psychiatrist father (Mendelsohn) tries to control her highly-strung mother (Davis) with various tranquilisers.

Events are broken up by a rapid succession of little title cards, one every couple of minutes. They often place an ironic distance between the audience and the characters, which softens gradually. The film lulls you slowly into its emotional core, but the emotional core turns out to be more conventional than you were led to expect. Ultimately though Babyteeth is all about the four central performances, which are exceptional.

4/5 stars
