Viewers generally appreciate 'Insomnia' for its intense psychological depth and strong performances, particularly from Al Pacino and Robin Williams. The film's exploration of moral ambiguity and the psychological manipulation between characters stands out, creating a compelling narrative. However, some felt the plot was somewhat predictable and lacked the complexity expected from a Christopher Nolan film, describing it as a good but not groundbreaking thriller.

👍 Strong performances by Al Pacino and Robin Williams.

👎 May lack expected complexity for some Nolan fans.
