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.

Output: no


Input: Consider Input: Review: Ok, after reading a couple of reviews on Atlantis: The Lost Empire, I just want to clear up some misunderstanding as to it being a direct rip off from Nadia: Secret of the Blue Water. The only part that was a ripoff from Nadia is that the pendant from Nadia and the pendant from Atlantis bear so much resemblence in terms of how it's used, origins and how it's created from the source of life that there's no doubt about it being copied. If you want to consider how Kida and Nadia is dressed alike then you could put that against Disney too(It was kind of wierd for Nadia and Kida to wear that bikini style clothing in an adventure sci-fi, not to mention they both move in a similar style too). As an anime fan I have to agree there's some degree of copying but it's only on the minor details and even though not many of the ideas are original (like the encryption design on the wall in Laputa, the ancient mask from Princess Mononoke, the resemblence of the vehicles to the Garfish submarine in Nadia, etc)...The plot itself I believe it's highly original and it's quite amazing that Disney can pull it off without the use of Captain Nemo(the main character in Jules Verne's 20k Leagues Under the Sea which is also the main character in Nadia). As for Mylo and Jean wearing similar style glasses...As shown in the novel "Lord of the Flies", glasses is a symbol of wisdom and intelligence. I think Mylo, Jean, the main character from Stargate and a dozen of other "INTELLIGENT" characters would look kind of unfit for the role if they went in without glasses. As for the submarines, and how the submarines fight(with those wide blast torpedos which really resembles what Nautilius does), I want to state that it's a required element for either one if Atlantis is involved in the plot(after all it's a sunken city beneath the waters). As for the crew having some charactistical resemblence with the crew from Nautilius in Nadia, it might be the artwork but I don't sense any copyright infringement there as the character's personalities were perfectly original to me. As an anime fan that rated Nadia as the #1 best anime I ever watched even now today. I do have my doubts about Atlantis when I first saw the preview. But now that I watched the movie, I once again regained my confidence with Disney and have high hopes for their future movies after Atlantis. Overall, the best Disney movie yet without me shivering at the sound of their songs at the middle of the movie and it's a plus that they revised their cheesy scripts to make it even better. Also, it's amazing that they actually portray the bad guys look normal with out making them overly evil in the beginning (I was wondering who the bad guys are and only the blonde girl kind of resemble the looks of a bad character in terms of how Disney draws it aka make the bad guys look really menacing) Question: is it a positive review?

Output: yes


Input: Consider Input: Review: If you want to see a retarded homosexual Karate expert beat up a bunch of try hard wannabe Mexican gangsters repeatedly for an hr, then this is the film for you. if not then choose another DVD from the 20c bin which is the only place this film belongs. the acting was so horrible that i had to force myself to watch it to the end. The cover makes it look so cool but its just another cheap, b grade gangster film along the lines of 2 g's and a key, bloody streetz and menace. I would not buy or rent this film unless you are planing to get stoned and plot , editing and acting really don't matter to you. it is truly the worst film in the history of humanity!!!
