Review: I don't hand out ten star ratings easily. A movie really has to impress me, and The Bourne Ultimatum has gone far beyond that. Furthermore, this trilogy has come together so nicely, that I believe it to be one of the greatest motion picture trilogies of our time. Though all three films could not be any more different from the Ludlum novels, they still stand as a powerful landmark in cinematic achievement. The Bourne Ultimatum made me want to cry that the series was complete, yet I could not even attempt to stop smiling for hours.From the moment that the opening title appeared, I knew we were in for a ride. Paul Greengrass has done it again. Everything we love from the previous Bourne films is here once again: the action, the dialogue, and of course the shaky camera. However for me, that last one was never a problem. I think it adds to the suspense.I will be back to see this film several times before it is released on DVD, simply because it is genius. It is a perfectly satisfying conclusion, and should stand the test of time as a fantastic movie, and altogether, an unforgettable trilogy. Question: is it a positive review?
answer:
yes

Review: Yuck! And again I say...YUCK! The original version of this movie was a well directed story of a man who was already dead and driving through purgatory. The original movie had a lot to say and didn't go out of its way to say it. And, it had a naked chick on a motorcycle.This version strikes me as something that a producer bought the rights to and then abandoned out of disinterest. It looks as if a group of individuals consciously decided to fit it to the nineties and changed ethnicities and genders just to be cute. The movie is not about a burnout about to commit suicide in a last act of defiance. It is about a man trying to get to a hospital to see his wife.There was no reason for this movie to have been made other than to make me angry... Question: is it a negative review?
answer:
yes


question:
Review: An incoherent mess with a gratingly deafening sound track, "Soul Survivors" is the latest entry in the "who's dead and who's alive" genre of horror films. Two teenaged couples, Sean and Cassie and Matt and Annabel, prepare to go off to different colleges, but before they part until Thanksgiving Break, they attend one last fling at a rave-type party in some burnt-out church at the suggestion of lusciously slutty Annabel (Eliza Dushku, a.k.a. Faith, the other vampire slayer). Motiveless creepy guys start paying far too much attention to Cassie (the generic Melissa Sagemiller) for reasons that are never explained, and before long, the quartet leave the party. Driving away in their SUV, they are pursued and then passed by the motiveless creepy guys, who promptly and inexplicably do an intentional 180 in the middle of the highway, causing a nasty and fatal accident as the SUV flips over an embankment and plunges into a river. Sean is killed (or is he?), and Cassie spends the rest of the movie coping with loneliness and guilt (she was driving) when she's not being haunted by Sean's ghost or chased by those motiveless creepy guys. Much unexplained incoherence follows as Cassie's mental state degenerates further, until we reach the predictable conclusion. So, who is dead and who is alive? After ninety minutes of this purgatory, who actually cares? Question: is it a positive review?
answer:

no
