At a glance: ‘Avatar’

A band of humans uses genetically engineered bodies to explore a distant planet in this effects-laden return by director James Cameron (“Titanic,” “Aliens”).

Running time/rating: 2:42; PG-13 for intense epic battle sequences and warfare, sensuality, language and some smoking

What they’re saying: “The King of the World sets his sights on creating another world entirely in ‘Avatar,’ and it’s very much a place worth visiting.” – Todd McCarthy, Variety
