A 6.3? What?
I just saw this film for the first time recently.
I have to say that the rating for this movie is shockingly low. I would have expected this to be at least in the 7s. The story is at times predictable, but then most movies are. This holds your attention the whole way through. Scott's direction is top notch, the cinematography is spectacular, and the whole atmosphere of Japan in the movie is extremely well done. The acting jobs were also very solid all around.
Black Rain isn't as innovative as some of Scott's other films but it is perfectly executed for what it is. It should be approaching the top 250, not languishing with a 6.3.
