“Girl At The Window” (** out of four) was a lukewarm suspense thriller about a girl (Ella Newton) who becomes convinced that the new man (Vince Colosimo) her mother (Radha Mitchell) is dating is the dangerous serial killer who has been preying on the town and sets out to prove it. Elegantly constructed thriller has various homages to Hitchcock’s “Rear Window” but never shifts into high-gear and is weakened by extraneous elements of unpleasant violence. Also known as “The Clockwork Killer” but either way is hardly worth your time.
