Q: Review: Nine minutes of psychedelic, pulsating, often symmetric abstract images, are enough to drive anyone crazy. I did spot a full-frame eye at the start, and later some birds silhouetted against other colors. It was just not my cup of tea. It's about 8½ minutes too long. Question: is it a negative review?

A: yes

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?

A: no

Q: Review: I am writing this after just seeing The Perfect Son at the 2002 Gay and Lesbian Mardi Gras Film Festival in Sydney, Australia.When their Father dies, two estranged brothers meet at the funeral and after discovering that one of the brothers is dying from AIDS, they enter on a heart warming journey of reconciliation. The two leads do a magnificent job of creating the gradual warmth and respect that builds up between them as the movie progresses. I do have one qualm about the movie though - whilst the brother who is dying acts sick, he doesn't look it. A person of 0 T4 cells would look quite ill - not even a make up job to make the actor look ill was employed. A small gripe, but one that makes it a bit less realistic. Despite that one small gripe, The Perfect Son is a wonderful movie and should you have the chance to see it- do. I'm hoping for a DVD release in the near future! Question: is it a negative review?

A:
no
