My verdict: This movie wasn't fabulous, but I liked it just fine. It had some nice twists (though I figured most of them out beforehand) and some pretty impressive action sequences. Angelina Jolie as a blonde looked like an aging Darryl Hannah (i.e. not very good). The intent of the sleepers was implausible. If you kill everyone except the President in his bunker and launch missiles against Mecca and Tehran, there's no way Russia is going to avoid fallout—it was obviously Russians that did this, not the United States. The love story was also a little hard to swallow—especially considering the intense conditioning the sleeper agents received in the Soviet Union.
