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.

Review: I have loved this book since my 5th grade teacher read it to our class many years ago. And I have read it to every one of my 3rd and 5th grade classes over my past 18 years of teaching. Supposedly a movie had been made in the past, but I'd never been able to locate it. Well, my students and I were all so excited when we heard that Disney had brought Madeline L'Engle's excellent book to the screen. As I watched the movie, I had the highest of hopes. As the film went on, I became more and more despondent. They had botched it badly! Never had I been so let down by a favorite book-to-film adaption. I understand that films can't stick strictly to a book, but they don't need to change things for the sake of it! Most, if not all, of departures from the book were totally unnecessary! I kept my opinion to myself at first and just listened to my students discuss the movie. Well, it wasn't just me. Nearly every single one felt the same way--cheated out of the great story that Madeline L'Engle had so skillfully created! Why, they wondered, did Aunt Beast look like Chewbacca from the star wars movie? Why couldn't Calvin's hair have been red? Why did Mrs. Which not have the proper "witch-like" outfit that was such a clever play on her name? Basically, we all wondered--why did nearly every single detail have to be changed? I have always dreamed of how wonderful a movie this book would make. I am still waiting for that movie. This one was A Wrinkle in Time in only the broadest of senses. I'm going to write to Peter Jackson and try to convince him to take on the task! Question: is it a negative review?

Review: When I decided to watch THE BARBARIANS, starring those twin bodybuilders, Peter and David Paul, I thought it couldn't be that bad because the film was directed by Ruggero Deodato, who has a reputation for creating sleazy movies but well made sleazy movies. Well, THE BARBARIANS is remarkably trashy action/adventure movie that wants to be another CONAN THE BARBARIAN, and fails at every level. The look of the film is all wrong. Some scenes were well shot but the tone and the schintzy, tacky "disco" look of the clothes and hair people are adorned with just doesn't make any sense whatsoever, even for a low budget flick like this one.Richard Lynch looks like an old woman with that ridiculous hairdo and costume. He's supposed to be menacing but he comes across as a buffoon. And it's funny to see Eva LaRue Callahan, one of the stars of ALL MY CHILDREN, appear in her first movie, walking around in skimpy fur bikini. I'm sure she wants this dreck to disappear from the face of the earth! The so-called Barbarian twins are okay as the muscle bound heroes but it's almost impossible to construct a proper critique of their acting because their roles are, like everything else in this mess, really ill-conceived. The only way the film tries to differentiate one twin from the other is by having one twin wear a loincloth that covers his ass, while the other twin's loincloth barely covers his muscular butt. I'm not kidding! Don't ask me who's who though.Deodato must have been really desperate to agree to make this film. And his desperation is reflected perfectly in this trashy flick. It's just bad.
