"Troll" is a horror-fantasy film that weaves traditional elements of supernatural and monster genres with a familial setting. Typical elements include a menacing creature—in this case, a troll—that uses dark magic and possession, adding a layer of mythological horror. The storyline involves an innocent child being taken over by the troll, which is a classic trope of vulnerability and innocence threatened by evil forces. What makes "Troll" stand out from other horror titles is its blend of fantasy with horror, involving a troll's attempt to build an army and control the planet, which expands the scope beyond simple terror to a more epic, otherworldly conflict. Additionally, the narrative includes interpersonal drama hinted at by the troll's connection to Eunice St. Clair, adding complexity to the antagonist's background. The setting within a San Francisco apartment building grounds the supernatural events in an urban environment, making the horror more intimate and immediate.
