[EX Q]: Review: don't watch this Serbian documentary and Serbian propaganda look out for this documentary and you will see facts and truth. The Death of Yugoslavia documentary series (of five episodes) is a painstakingly compiled and researched account of the extended mass-bloodshed which marked the end of the old Federal Yugoslavia and spanned almost the entire first half of the 1990's. It includes a huge wealth of news footage and interviews with involved parties both "Yugoslav" and otherwise. The only real "improvement" which could be made to this amazing achievement would be the inclusion of later developments in the Balkans since the program was made. This was indeed done in the late 1990's for a repeat showing on BBC television, but the addition of some even more recent events would help to complete this admirably detailed and fulsome piece of work. Perhaps another whole episode might be warranted? The very succinct title of this documentary was made all the more appropriate by the eventual abandonment of the term "Yugoslavia" by the now-named Federal Republic of Serbia and Montenegro - a much belated and formal admission of that which occurred years before.not fiction like in "Yugoslavia: The Avoidable War (1999)" Question: is it a positive 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

[EX Q]: Review: A well-made and imaginative production, refreshingly free from cliché, this somewhat picaresque affair recounts a tale of a close friendship that develops between a man and a boy under less than ideal conditions: the man an escaped convict who has kidnapped the youth for his value as a hostage. Expertly directed by Alan Gibson with a fine sense for balanced narrative movement, the film provides freshness in nearly every scene, as felon Martin Steckert (Richard Harris), believing that his rejection for parole was particularly undeserved, contrives a convoluted but ultimately successful escape plan, following which his spontaneous nature comes to the fore as he flees to the lakeside residence of his childhood. Often bursting into song or dancing a few steps, the capricious Steckert gradually gains the trust and affection of his captive and, as police close in for an inevitable showdown, the tethered pair are seen to be a great deal alike in their responses to forms of rejection, as discerned by a psychiatrist (Lindsay Wagner) assigned to aid a zealous police lieutenant (James Coburn) who is in charge of the manhunt for Steckert and his "prisoner". This is an engrossing story, worth telling, a quickly-paced and novel adventure that profits from a capital performance by Harris, fine turns from Wagner, Coburn, and Karen Black, along with Justin Henry as the snatched lad, with an appropriately whimsical score contributed by Wilfred Josephs, and top-notch cinematography by Frank Watts, with all footage shot in a beautiful autumnal Ontario province.

[EX A]:
yes
