James Franco in Oz the Great & PowerfulOZ THE GREAT & POWERFUL

As numerous effect-heavy entertainments have proved over the years, few film actors, and even fewer good ones, look altogether comfortable performing in wholly pixelated landscapes opposite wholly digitized characters. Yet I'm not sure I've seen any star look less connected with his artificial environment than James Franco does in Oz the Great & Powerful, director Sam Raimi's mega-budgeted and intensely disappointing prequel to The Wizard of Oz.
