The film 'Nightbitch,' directed by Marielle Heller and starring Amy Adams, has garnered an overall positive reception despite a negative initial response to its trailer. Premiering at the Toronto International Film Festival, the film has received praise for Adams' performance, which critics describe as emotionally brave and darkly intimate, showcasing the challenges of motherhood. While the source material is a horror satire, the adaptation takes on a fantasy-tinged dramedy tone, leading to mixed feelings among viewers regarding its genre shift. Critics have noted the film's exploration of maternal struggles, with some expressing disappointment over its fantastical elements and visual execution. However, many agree that the film is far better than its trailer suggested, and it holds a commendable score on Rotten Tomatoes. Overall, 'Nightbitch' stands out as a significant showcase for Adams' acting prowess, with audiences encouraged to overlook the unflattering trailer.
