Guys, reading your comments I want to watch Insomnia again, even if I've seen it a dozens of times. So... I can't stop myself. Watch it right now! Love the atmosphere, Pacino, Robin WIlliams, David Julyan's music, editing, cinematography... If I've be honest I like it more than Dunkirk and Batman Begins.
Some people just want pepsi twists and mindfucks and Insomnia doesn't give that.
I've said it once: majority (?) likes Nolan just because of "twists"
I don't think that's why. Batman Begins's twist and The Dark Knight Rises's twists are both very mediocre. It's nice having Liam Neeson came back but nobody's like "Oh my God, I was convinced it was Ken Watanabe!". The Dark Knight doesn't have a twist and people like it the most. Dunkirk doesn't have one either.
I think people don't like Insomnia because it's his least unique. It feels like anyone could have directed it. It's almost generic. I personally don't like the soundtrack and I remember the overall story between Al and Hillary to be predictable and slightly corny.
