A fierce subject gets a fairly tame close-up in director Sue Kim’s Always Lalisa (B-), a documentary whose star power outshines its powers of observation. Following BLACKPINK performer Lisa (the “rapper” in a K-POP girl group) during a relatively brief stretch of her burgeoning solo career, the film offers a snapshot when its compelling subject and the nuances of her cultural background and work ethic warrant a fuller portrait. Lisa’s formidable presence supplies the spark, but the filmmaking rarely turns that electricity into illumination. The narrow timeframe needn’t limit the insight, yet Kim struggles to make this chapter reveal much beyond its immediate circumstances. There’s enough charisma to hold attention but less discovery than one might hope from such proximity to a global phenomenon. It also needed more music. It’s Always Lalisa, occasionally revealing.
