In sombre yet brightish Brit drama "A Bit Of Light" alcoholic Anna Paquin (decent - despite her Kiwi accent kicking in) loses custody of her kids to ex Youssef Kerkour & his new partner Pippa Bennet-Warner. She lives back with dad Ray Winstone (surprisingly restrained - he's excellent) who like Kerkour & Bennet-Warner wish her well - but her demons haunt her. These dynamics work, but in adapting her own play debut writer Rebecca Callard (who also cameos) then throws in toady teen Luca Hogan as an unnecessary & annoying main character. Still, director Stephen Moyes brings it all home warmly, and despite those flaws it's interesting & engaging enough (just about).
