Input: Consider Input: Review: I really enjoyed this film because I have a tremendous interest in American History... the Antebellum years and the Civil War in particular. I purchased it recently from a rack of previously-viewed videos on sale at the supermarket and I was very glad to add this one to my history video collection. Though not of the caliber of Civil War films such as "Glory" or "Gettysburg," provides a lot of history on the pre-Civil War brotherhood among cadets at West Point.Maybe it's the gray uniforms, the youth, or the military discipline, but I am fascinated by the story of the Corps of Cadets from around 1830 to the brink of the War. I imagine what it must have been like to sit in a classroom with other young men, learning how to make war, then later putting the lessons to use against your own classmates!Actually, there were two classes graduated in 1861: one class in May, the other in June. the movie makes no real mention of this, except to mention Henry A. DuPont, first graduate of the May Class; and George Custer, last grad of the June Class. the reason for the two classes was not so much about the war, but it was the result of switching back to a four-year course of study, after a few years of experimenting with a five-year course (I think the first class had attended five years, the other for four). As the movie portrays, cadets were like brothers and often had nicknames for each other... George "Fanny" or "Autie" Custer; Alonzo "Lon" Cushing; James "Beauty" Stuart (for J.E.B. Stuart, class of 1854), etc.I say this film is "Santa Fe Trail" as it should have been because that 1940 film, while enjoyable, really fudges history. Cadets from several different classes are all graduating together. JEB Stuart and George Custer are portrayed as the best of friends and are side-by-side in stopping John Brown's 1859 insurrection at Harper's Ferry. In fact, Stuart and Custer were never friends, but enemies during the War. They faced each other (for the first time, I think) at Gettysburg in 1863 (Stuart was at the Harper's ferry Raid, but Custer was still a cadet at the Point when it took place)."Fanny" Custer plays a role in "Class of '61," though his classmate chums, Dev O'Neill and Shelby Peyton are fictional. I believe they are respectively based on Partick Henry O'Rorke and John Pelham, two people you can look up.Anyway, I truly enjoy this film or any film which provides a window into mid-19th Century America.

Input: Consider Input: Review: This couldn't have been better. The strong restraints on Mike Sullivan's expressions couldn't have been portrayed in any other way. Tom Hanks delivers the best performance of his career. Young Tyler Hoechlin drives an emotional wheel; playing the basis character for the story. And veteran Paul Newman gives one of his best character performances in a long time.This film is based on a bold graphic novel by Max Allan Collins and Richard Piers Rayner. This is a father/son story which basically employs the two candidates solely unfit for the roles. Mike Sullivan had no father as a child, so John Rooney took him in. Although a generous man, Mr. Rooney involved himself in organized crime. Therefore, the debt of Sullivan was only to be paid off in involving himself in the business. Now, Sullivan has a wife and two children and is trying to keep his children safe, but at the same time pay back his boss. The events to follow, will test Sullivan's loyalty and embrace his family's fate.With a great adaptation by David Self, the dialogue comes out seldomly, but yet very virtuous. The story unfolds in a beautiful 1930's setting (Brilliant Art Direction by Richard L. Johnson & Nancy Haigh) covered with a dark rainy (snow on the ground) exterior. Driving the story, is Thomas Newman's wonderful Irish score, settling in only when necessary.But the most important technical element in the film is Conrad L. Hall's beautiful photography. This is some of the best cinematography I've seen; and I watch a lot of films. The scene when Mike and Michael are in the car, entering Chicago is quite impressive. The shot starts at the front of the car, revealing Mike(Hanks) through the windshield. It subsequently dollys around to the side of the car, to see Michael(Hoechlin) awakening and peering out his side window. As it continues, it trucks sideways and dollys back, completely around the car and reveals a gorgeous scenic 1930's Chicago.With a great cast and crew, the principle man creates a brazenly amazing film. I'm talking about Sam Mendes, who made his feature film debut in 1999 with American Beauty. (won him various awards) Before American Beauty, Mendes worked as a play director for the British Theater, but decided that he wanted to move on saying that there was nothing new for him in theater. With only two films, Sam Mendes has marked himself in my book as one of the great directors (In a list of about twenty-five).The film illuminates a brazen genre that has its hits and misses and expresses the true theme brilliantly. The photography, acting and story is phenominal. I'm still waiting for Scorcesee's Gangs of New York, but for now, I'm fully confident in saying that this is the "Best Film of the Year". Considering it's competition (Signs, Insomnia, Minority Report) thats a strong statement. Question: is it a negative review?

Output: no


Input: Consider Input: Review: This is one of the worst films I have *ever* seen! It is bad, even at TV Movie level standards. The plot is diabolically flawed, and the known names in this film are wasted on confused, uncertain characters. I don't know how the director managed to keep this excuse of a film together - it is that bad. Billed as a 'Psychological Horror Thriller' - it is certainly Horrific. There is nothing Thrilling about it. And it could do you Psychological damage! The initial opening scenes held such promise - a possible embarkation on whether the soul is just an aspect of the brain, but the utter shambles that followed the car-crash scene is beyond belief. No matter how hard you try, you couldn't care less about the characters. There are so many sprinkled ideas that the film is at best a collage of disconnected phrases from Chinese philosophers, and at worst the film would actually make you go Brain Dead!I have purchased over 300 films on DVD, and this is the FIRST one I'm going to get my money back on. STEER CLEAR. Question: is it a negative review?


Output: yes
