Matrix1: Keanu in really rather good and groundbreaking action movie shock. Goes "Woah" a few times, does Kung fu and shots lots of guns a lot and kills Hugo Weaving
Matrix2: Keanu in pretty average and surprisingly dull action movie. Goes "Woah" a few times more, shoots more guns and kills Hugo Weaving over and over and over and over again. Some bloke pretends to be french. Whole audience of Cinema wants to slap him.
Matrix3: Keanu in pointless and dull action movie. Cant say as to whether he went "woah" a lot as I couldnt be @rsed to actually watch this after being thoroughly bored during Matrix2 and didnt feel like wasting a night out at the flicks or insulting my inteligence and blowing £12 on a dvd but, as its a Keanu movie I would expect he did actually go "woah" quite a bit in this one too.
Personally I'd watch Dark City any day
