“The Hunger Games: Mockingjay – Part 1” pulled in more than $336 million during its U.S. theatrical run, edging out “Guardians of the Galaxy” to become the top-grossing film of 2014. Nobody should confuse box office success with quality, as these things rarely relate, but “The Hunger Games” pictures have been solid. Unfortunately, “Mockingjay” is a letdown in comparison to the previous entry in the franchise, “Catching Fire.”
