Released last week, “The Hobbit: An Unexpected Journey” has ushered in the ever popular Christmas holiday movie season. Peter Jackson’s follow-up to the “Lord of the Rings” trilogy has been packing movie theaters since its first midnight showing Dec. 13.“’The Lord of the Rings’ was such a big franchise and so many people are coming through here just very excited about it,” said Mike Melloy, assistant manager at Movies 400 in Cumming. But with Quentin Tarantino’s latest movie, “Django Unchained” and the star-studded second silver screen rendition of Broadway’s “Les Misérables,” set to open Christmas Day, “The Hobbit” will have healthy competition as it fights to maintain the top spot.
