Some solid releases are making their way to studio shelves this week. The top titles include: Public Enemies [Blu-ray review]- one of director Michael Mann's greatest achievements: an experimental French New Wave riff cleverly disguised as a summer blockbuster; Harry Potter and the Half-Blood Prince -the penultimate book in the Harry Potter series gets the big-budget treatment in this impressive film; and Julie & Julia [DVD review, Blu-ray review] - a confection: light, sweet, and airy. Other releases of note include:  Lost: The Complete Fifth Season [Blu-ray review], Hollywood, Je T'aime [DVD review], and Johnny Mercer: The Dream's on Me [DVD review].
