[EX Q]: Review: Grand Canyon is a very strange bird. It's a completely unique urban piece, where relating the entire plot would fail to convey much.It's central theme seems to be the inherent uncertainty life holds for people of every race, background and station. But to proclaim that THE theme of the film would be to horribly understate its scope. Similarly, to pigeonhole it in a particular genre is futile.The film has volumes to say, though likely different volumes for every viewer, and says it all in such a non-preachy way from so many angles, that in the end, i can't even define its central message for myself.Nevertheless, it does it's business with such laser precision; every prop, line of dialog, and bar of background music contributing to it's pervasive mood and powerful message, that i'm pleasantly surprised, and come away very thoughtful after every viewing. Still it doesn't feel at all stuffy. A sparkling film with a great cast and everything working. Question: is it a positive review?
[EX A]: yes

[EX Q]: Review: It looks to me as if the creators of "The Class Of Nuke 'Em High" wanted it to become a "cult" film, but it ends up as any old high school B-movie, only tackier. The satire feels totally overshadowed by the extremely steretyped characters. It's very un-funny, even for a turkey. Question: is it a positive review?
[EX A]: no

[EX Q]: Review: There is no such a thing as perfect murder.Lieutenant Columbo knows that.Ken Franklin, who is the other half of the writing team of detective stories doesn't know that.He kills his partner Jim Ferris who had plans on going solo.Now Columbo steps into the picture and asks all sorts of questions from Mr. Franklin.And returns for one more question.Columbo: Murder by the Book (1971) is directed by the young Steven Spielberg before his days of fame.Steven Bochco wrote it.Columbo is a fantastic character with his shabby look.It's hard to believe this man could solve any crime.But he could.Each and every one of them! Peter Falk is the one and only person in the world that could portray this character.So no remakes, please.This part is a very good example of how Columbo worked.Jack Cassidy plays the murderer and Martin Milner plays the victim.Rosemary Forsyth plays the victim's wife Joanna Ferris.There's something endearing in the scenes between Columbo and her.How he makes the omelet and everything.Barbara Colby plays Lilly La Sanka.She actually met a tragic fate when she died after a homicide like she does here.I've been a fan of Columbo since childhood and I still enjoy watching them.There was a break for many years that they weren't showing Columbo stories at all but now he's back.Back for one more question. Question: is it a positive review?

yes
