great visual effects, not as groundbreaking as in the first movie but maintaining its own style (the neon thing) in up-to-date graphics. astonishing action scenes!
as in "the curious case of benjamin button", one actor performed characters in extremely different ages thanks to visual effects, though here one of them was limited in facial expressions, which was very convenient..
as in the first movie, a terribly simple story about good and all the adventures to defeat evil. some of the nerd/geek terms were put aside in this sequel, while the religious aspect of the "user" was improved. now, besides the mysterious "user", we have the powerful "creator", the miraculous "ISOs" and the "fallen angel" clu. yeah, a bit repetitive but maybe a sign of a mature story coming in the next sequels (i think i've seen a cliffhanger ending).
