Example 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. Question: is it a negative review?
Example Output: no

Example Input: Review: This is one of those cheaply made TV Movies were the characters seem to lose all sense. The premise of the story, the kidnapping of a son by the boy's father,is very good. But the story just seems to beggar belief. Whenever the mother is advised not to do anything you know fine well she is going to do it. It is a bit far fetched and not worthy of a viewing. Question: is it a positive review?
Example Output: no

Example Input: Review: There are just so many things wrong with this movie.To begin with, the first twenty minutes of the film could have been compressed into just five or maybe ten. The overall movie is (mercifully) short already, but this could have been made up for by giving a little more attention to the Mean Lion (how did the miss a reference to "The Wiz" on that one?) and working his subplot a little more closely into the main plot. In short, the script had the seed of a good idea, but needed quite a bit of reworking.Second, it could have done without the crude humor. The original also had some that it could have done without, but at least there it was almost an afterthought -- here, flatulence and urination abound.Third, the show is a little too self-aware. The original series had that well enough, as did the first movie, but here it's just way, way too much. The Brendan Fraser in-jokes were just a bit over the top (and why no mention of the "new Ursula"?). Other gags with the Narrator, especially a couple of interactions near the end, also exceed good sense.Fourth, a bit more attention could have been given to the CGI work. In the first it was hard to tell that Shemp wasn't a real elephant (except by behavior, of course), but here the CGI stands out like a sore thumb. Ideally special effects should merely tell the story whether they're good or bad, and they at least do succeed on that count, so it's a relatively small problem, but it's still there.All that said, Christopher Showerman's performance as George is decent enough. It lacks Brendan Fraser's charm, but Christopher only really fails in that specific comparison -- he even managed to give George a bit of personal depth, which should have been a major foul in a Jay Ward-inspired movie but wasn't here. Julie Benz as the new Ursula surprised me as being even better than Leslie Mann in the original.Most other performances were pretty standard, not standing out in my mind as either good or bad.
