[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 think this is almost all I need to say. I feel obliged to explain my actions though. I've basically never seen such an armateur production, and I mean that in all senses of the word. Although the physical camera work, boom MIC operation and other technical aspects of this film are laughable, unfortunately its not the only areas.Unlike some classic independent films that have been saved by their scripts great characterization and plot, this unfortunately has an awful script, awful acting and worst of all, awful annoying characters.It's a crime that for the every independent film that gets, distribution like Haiku Tunnel, there's a 101 other indie films that died silent deaths. I don't know who the Kornbluth brothers know at Sony, but that can be my only explanation as to how this amateur family production ever got distribution. I'm quite bemused as to why they picked this up.The ONLY part of this film that holds out any intrigue is its title. However, the reason for that is even a let down. I hope this review will save a few people that may be intrigued by this films title from going to watch it. I've seen a lot of films in my time, and I'm very forgiving when in the cinema, but this was too much. I'll never forget 'tunnel', for marking an important point in my life experience of cinema. Shame it's such a low point. Question: is it a positive review?

[EX Q]: Review: Allow me to start this review by saying this: I love vampire movies. They can suck (har har pun intended), and I'll still love them because vampires are just cool in movies. Van Helsing, considered by many to be a steaming pile of crap, was enjoyable to me because of the fact that there were vampires. You may ask: "What does that have to do with this movie?" The answer is that I intend to inform you of how horrible this movie truly is, that even a sucker (harharhar) for vampire movies like me can despise a movie like this so much.The movie stars Van Helsing, a college professor guy who isn't at all convincing. He's a terrible actor, like everyone else in this movie, and he wrote it, to add salt to the wound. I honestly to not mean to offend him, and I'm sure everyone had fun making this movie, but watching it was actually painful. I'm not sure why I watched the whole thing; perhaps it was a morbid fascination, like watching an impending train crash: it's horrible, but you can't manage to force yourself to look away. Its main fault is that it's just so ****ing boring, and its plot is so damn ridiculous, even for a science fiction horror movie.But, I digress. By the way, Van Helsing has sex with his mom. Of course, he doesn't know it's her at the time; he just thinks it's one of his students (which is still illegal and all, but not as disgusting and creepy).If I were Van Helsing, I would at least pull an Oedipus myself when I found out I had done something so gross. It would've made for one entertaining thing if he just made some comment on it, but no. The point isn't even brought up at all, by any of the characters. It's as if the writer didn't even think of it. I would've at least had another character laugh at him and say "Ha ha, you had sex with your mom," which would be mildly humorous (although blatantly immature). I'm probably running out of room, so a few more words to dissuade you from ever seeing this film: there's a vampire ninja fight with an old man. It would be funny, but the filmmakers expect us to take it seriously. It's not even worth watching the movie to see how bad it is. Stay far, far away from it if you value your time at all.I will say one thing positive about the movie: the guy who plays Van Helsing is pretty slick with that knife of his. There's like, a minute long segment where he swings around his knife and actually does some pretty nifty tricks. It would be boring in any other movie, but here, sadly, it was the highlight.
