After going through a spate of serious movies, we decided to have fun tonight and rented Johnny Mnemonic, chiefly because I'm a big William Gibson fan, and I have a fondness for Keanu, too.
You probably know that it's not a heavyweight contender, but the villains are satisfactory (if one-dimensional), Keanu looks impossibly handsome, and there are some slyly witty moments, such as Keanu's heartfelt plea to the gods: 'I want room service!' which puts to rest the canard that he can't show emotion.
The film is based on a short story of Gibson's set in the near future, where information is currency and neurological implants the order of the day. I wish his ideas got the treatment they deserve, but I suppose it's too much of a temptation to concentrate on the action/adventure and campy SF elements instead of the philosophical implications.
