Definition of «heavy lifting»

"Heavy lifting" is a metaphorical phrase used to describe a single element of a creative work that is doing most of the work to make it successful or believable. In internet criticism, it often implies that a specific actor, a single word in a title, or a particular visual effect is carrying the weight of an otherwise weak project. The tone can be slightly cynical, suggesting that the rest of the work is lacking in quality or effort. It points out a perceived imbalance where one part of the production is over-performing compared to the rest.
