Just watched it yesterday night with my wife. We only found a cinema which started the fim at 22.30h so it was running till nearly 2am!
Yet, apart from some scenes in he middle where I felt the film was indulging too much in its great visuals, we both loved it and didn't regret a single minute.
It might have been tighter without Harrison Ford, though, and I didn't get why the Replicant rebellion was in it, and neither the part of Jared Leto.
Yet, these are minor criticisms to a truly epic movie that carefully and cleverly spun a sequel to one of sci fi's all time classics!
