Julia has an unconventional anti-hero in the shape of a drunken, aging, slapper. She'd be a `grenade' but that would require her to have some mates. We're introduced to her with a day-in-the-life passage of her getting paralytic at a party, shouting obnoxiously, making a nuisance of herself and then taking the least judgmental man home with her, washing off the stench of failure from the morning after, getting sacked.
After being forced to attending an AA meeting she becomes aware of the existence of a crack-pot nearby neighbour. Only then does the movie becomes an awesome seat of your pants, on the fly, ransom / kidnapping story.
'Julia' takes an unsavoury character and had me rooting for her by the end, even when she manages to blow half of her opportunities to pieces. Everyday traits, like spinning off ludicrous yarns to get what she wants, now work for her. In the face of immediate danger the distortion of truth remains the only way for her to regain control of the boy.
I thought the finish was coming up at the 100 minute mark, but then it pulled the rug out for underneath me and went on for another 40 minutes and I couldn't be happier! Usually continuing past the expected point of expected climax is the death kneel for a film, but Julia got me so invested in the character on screen that I wanted it to keep going and going. When the credits finally did roll I was disappointed, just because I thought the film had some gas left.
Tilda Swinton puts on a one-woman show (Ala De Niro in Taxi Driver) as she's literally in every scene, so if you dislike her, avoid, otherwise, enjoy the ride.
