Pennu Case, directed by Febin Sidharth, introduces Rohini, played by Nikhila Vimal, as a con woman committing marriage fraud in Kerala and Karnataka. The movie begins with this premise but struggles to show how Rohini tricks her victims or makes her escape. A police team headed by CI Manoj maps her targets but the film gives little on her actions after the weddings. Rohini's excuse of camera shyness to avoid wedding photos is one of the few clever ideas. Only in one case does the film show Rohini convincing a man she is perfect for him, but the scene lacks imagination. The writing and directing seem half-hearted throughout the film. Many scenes, including those meant to be funny, fail to entertain. Contrary to its promotion, Pennu Case stays serious for most of its 112-minute runtime. Similar to the series Nagendran’s Honeymoons, the film does not fully explore its marriage fraud concept. The plot saves details for a big twist in the end, which feels deliberately held back but not very original. Nikhila Vimal’s character has great potential that remains underwritten, and her calm acting does not fit the con woman role well. The movie’s deception fits the final twist but lacks excitement and borrows from a famous '90s film ending. Despite its flaws, it partly succeeds but ends up average.
