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?

Review: Saw this Saturday night at the Provincetown Film Festival, and it's a stick-to-your-bones movie -- it's really stayed with me. Adapted very smartly from what is probably an excellent novel, it's a back-and-forth-in-time drama with fully rounded characters, thoughtful rumination on life choices, and, I'm not exaggerating. one of the greatest casts ever assembled in 100+ years of movie-making. Wonderful work from everyone, led by a luminous Vanessa Redgrave as a dying, deluded Newport matron, and Claire Danes as her much younger self. Meryl Streep's daughter Mamie Gummer is, like Mama, the real deal; Patrick Wilson looks like Paul Newman circa 1958 and doesn't overplay the charm; and what a pleasure to see such excellent stage actors as Barry Bostwick and Eileen Atkins contributing sharp, detailed cameos. Hugh Dancy, also from the stage, doesn't bring much edge to the somewhat cliched role of an unhappy rich wastrel, and the family issues are resolved perhaps more neatly than real life would allow. But it's a deliberately paced, visually gorgeous meditation on real life issues, and you can cry at it and not feel like you're being recklessly manipulated. Also, what a sumptuous parade of 1940s/50s automobiles. Question: is it a positive review?

yes
