I love this film,keanu reeves has really excelled himself in this,the film is thought provocating,intense,has some brilliant fight scenes and the special effects are really cool.I was surprised to learn afterwards that keanu actually did the karate sceens,it took months to learn,when you watch it it's hard to believe it's real.The other characters are very good too,it's a totally believable film,if you've got imagination,and i would recommend it to anyone who like sci fi horrors and wants to have their opinions on the world challenged-the best film i've seen in a long time.
