The film does an impressive job of portraying human feelings, and the unusual setting along with strong performances contribute to making Insomnia an enjoyable experience, justifying its two-hour length. However, it didn’t impress me as much as it seems to have impressed some viewers. It's possible that if I weren't familiar with Nolan, Pacino, or Williams' best work, or if I hadn’t realized near the end that I had seen it before and only recalled the conclusion, then it would have resonated more strongly with me. Even considering my perspective, _Insomnia_ remains a well-made movie. _Final rating:★★★ - I suggest you check it out._
