[EX Q]: Review: I am very surprised to see such a high rating for this film, and of the few reviews that there are to be positive. I saw the movie and was pretty dissapointed. I didn't find it very enjoyable at all. It was slow, and lacks the entertainment value. Even the murder scenes are lackluster, with real close-up shots of generic stabbings that don't look good at all. And the supposed great twist ending is really not much, I did see it coming, and then the ending just seemed cliche. This movie may not get much mention, but by the little that it does get, it is overrated. I would not recommend this movie. Question: is it a positive review?
[EX A]: no

[EX Q]: Review: What's Good About It: Some inventive and genuinely creepy little effects that will get under the skin of even the most seasoned horror fan. Doesn't rely on the hackneyed soundtrack stabs for its "gotcha" moments. Even if you've seen everything, there's still a few things in this film that will make your jaw drop.What Could Have Been Better About It: The acting was, at times, flat and unconvincing. It had a "shot-on-video" quality in some places (though,it mostly achieved the atmosphere it was striving for), and the camera work is full of needless close-ups of meaningless actions. Though the effects are genuinely creepy, I think they may have gone to the well a few too many times with some of them. The ending seemed rushed, and glossed over what could have been more impactful moments. The viewer is left to figure out a lot of things for themselves, not as a challenge by the filmmakers, but because they just missed it.Still, a good little indie horror film that is easily several steps above the average. Well worth the rental. Question: is it a negative review?
[EX A]: no

[EX Q]: 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?
[EX A]:
yes
