[EX Q]: 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.

[EX Q]: Review: I have never commented on a film before. I watched this movie with my girlfriend last night. I've read comments saying this movie stays with you. It does. It's been almost 24 hours and I am still completely affected. This movie left me questioning my own self. How can I possibly compare myself to a character such as Ben who is totally selfless. I loved this movie. I love movies that keep me guessing and wondering until the end. I feel two emotions predominantly, happiness and sadness. An amazing feel good movie and a very sad one too. I so wanted Ben and Emily to be together, but in the end, they were, forever. If you haven't seen this movie, get it and watch it. Just make sure you have no distractions. You'll want to see every nuance in this picture. One for my library. Question: is it a negative review?

[EX Q]: Review: I saw this movie on the BIFFF Festival in Brussel, spring 2004. What a surprise! This German production, a stylish and imaginative shocker, is one of the scariest flic i have seen. Be warned: this is not a joke! This terrorizer has a big cast of good actors (as an example:Peter Martell as a European guru has a strong presence), excellent direction, nice production design, a very good soundtrack and a lot of heavy gore sfx like Italian horror movies in the eighties. Flesh ripped clean to the bone...and the blood runs red ...this savage Heart Stopper will grip you...and give you some dark dreams ... A must-see!! Question: is it a negative review?

no
