Anyone else find this less impressive on a re-viewing?
I've seen this maybe 3-4 times and I always remember thinking it was a really good movie until my most recent viewing when I came away thinking whatever cool ideas it had were drowned out in overdone action scenes with excessively stylized villains and too many of the secrets spelled out too literally.
I think it would have done its narrative a favor of the villains had been much more blended in with the population, and not leather-clad cosplayers from a Nosferatu convention. Kiefer Sutherland's character without his stilted speech pattern and gimp. And the mystery of the weirdness of the city and its inaccessible features much more of a mystery and more of the central focus of the film rather than Rufus Sewell's but-I'm-not-a-killer fleeing from William Hurt.
Like maybe the narrative is about Sewell waking up during a tuning and starting to question the nature of his reality and becoming obsessed with finding Shell Beach. The aliens live among humans to monitor them and are indistinguishable from ordinary people. They become clued into Sewell's growing awareness of the unreal aspect of the city and frame him for a murder. Hurt catches him right away, but Sewell turns him and the balance of the movie is them trying to get to Shell Beach but find that every route they know of is weirdly shut down. But in the process they discover the hidden reality they're on a space ship controlled by aliens who they figure out how to identify and eventually overthrow.
