Example Input: Remarkable!  Pure Visual Poetry . Sergei Eisenstein's Que Viva Mexico is a film that captures the majesty, awe, and tragedy of Mexico better than any other I have ever seen.  And it does so not with dialogue or plot, but rather thru "a sequence of short novellas" (Eisenstein's words) which each develop and play convincingly into the next.  Each of these vignettes to me display a celebration of real Mexican culture and a subtle depreciation of those things which came from Spain.  They evoke the heart of true Mexican patriotism as if it were struck directly from a Rivera mural.  For anyone interested in Mexico or Mexican cinema, Que Viva Mexico is an absolute must.        Que Viva Mexico is certainly one of the most famous "unfinished" films in history, with a tragic star-laced history about which whole books have been published.  In a few words, Sergei Eisenstein went to Hollywood but was almost immediately ostracized by the old studio moguls.  Douglas Fairbanks and Charlie Chaplin led him to the famed moralist, communist, and novelist Upton Sinclair, who agreed to finance a south-of-the border film.  The budget was $25k and shooting was to take four months.  Sinclair's brother-in-law was to tag along and supervise.  A couple of Eisenstein's Russians comrades would handle the cinematography and equipment.      Exactly what happened after that is a matter of some dispute, including countless cross and counter accusations of extremely lewd behavior and fabulous revelry.  What is certain is that after 11 months in Mexico the film was still missing its final section and Sinclair pulled the plug on the whole operation.  Furious, he then managed to block Eisenstein's return to America and convince Stalin he had been a poor communist.  Sinclair kept all the footage and Eisenstein was sent back to Russia in shame.    Eisenstein still believed he could make a great film out of his footage and fought to get it back, but Sinclair refused and had it edited by his own Hollywood producer.  From this work came the feature Thunder Over Mexico (1933) and the shorts Eisenstein in Mexico (1933) and Death Day (1934).  While these versions influenced great future directors like Welles, Huston, Bunuel, and Leone, they were not the real vision of the great director.  In the 1970s, the Russians finally got the reels, and Grigori Aleksandrov, who had been there and assisted with the original filming, put it back together following Eisenstein's original plan.       Back to the film, it is essentially a silent with narration, a music track, and limited sound effects added.  I don't have any problem with this as the alternative would have been to fabricate intertitles which would have been even less natural.  Anyway talkies were already completely dominant by 1932 and Chaplin used a sound effect track in all his later silents.  The musical track is sheer magic and certainly benefits from the extra years.  There is an abrupt break when the final unfilmed section is reached, before we are taken back to the Day of the Dead epilogue.  Frankly, I don't think much was lost here: Eisenstein was right when he said he didn't need that last segment to finish the film.  The third segment was already just a bit long, and adding the fourth (a continuation of the third) would have unbalanced the film.  Hence I would have just run the third segment straight into a more somber start of the epilogue.  But the way it was done does show us what was "lost", so in that sense it is valid.  My only qualm with this DVD is the fact that it doesn't have Spanish subtitles, as I think all Mexicans should experience this film!      One last thing:  the 1946 epoca dorada classic Enamorada by famed Mexican director Emilio Fernandez could be seen as a sort of tribute film to Eisenstein and Que Viva Mexico, as it basically fills out a story based on the sodadera lost segment of this film.
Example Output: POS

Example Input: Boring Fluff . I recently gave this movie another shot, at the request of a friend.  I was impressed, this time, with the beauty and consistency of the cinematography.  It's as if every scene could be a postcard, and the use of color and characters and costumes makes for decent viewing.  And the songs are great, if a little "forced" into the movie.    Unfortunately, that's all there is, except beautiful Brad Rowe, totally wasted here in this nothing piece about self-indulgence and galling disregard for everyone that loves you (while pining away for what you obviously can't have.)  Add to that a generous splash of feigned concern for others (Sean P. Hayes' character) while simply pursuing your own desires.  ("I want to be there for him.")  Right.  It's so artificial, it's about as convincing as plastic palm trees.      There are a few funny lines and nice dance numbers, but not enough to cover up the gaping holes and long, heart-felt pauses of nothing.      Someone made this picture to fulfill their dream, and did a fine job of casting and cinematography.  There is little else to see here.  Even as a fluff piece, it's barely worth your time
Example Output: NEG

Example Input: Eh. Not really. . Texas Chainsaw Massacre: The Beginning (Jonathan Liebesman, 2006)    In the documentary that serves as one of the DVD extras for Texas Chainsaw Massacre: The Beginning, a number of the movie's connections talk repeatedly about how their goal for this movie was to push the envelope with the gore. One even says that the people who went to see Hostel and The Hills Have Eyes (2006) will go to see this movie and expect the violence to be kicked up a notch. Well, folks, I just saw the unrated version of your movie, and I've only seen the rated version of Hostel. And I hate to break it to you but, well, even cut by the censors, Hostel blew you out of the water.    For those who have been living in a cave for the past thirty-two years, a quick plot summary: there's a very odd family living out in the middle of nowhere. When the main local business, a slaughterhouse, closed down, it took most of the population with it-- save this family. (The fact that the slaughterhouse is still in operation in the original film, and there are neighbors in some of the original canon films, seems to have completely escaped screenwriter Sheldon Turner [The Longest Yard].) As with any TCM movie, there must be a batch of clueless teenagers, here two guys-- Eric (Tru Calling's Matthew Bohmer), on his way back to Vietnam, and his brother Dean (Zerophilia's Taylor Handley), who's planning on ditching the war and heading for Mexico-- and their girlfriends, Bailey (Diora Baird, recently of Wedding Crashers) and Chrissie (The Fast and the Furious' Jordana Brewster), respectively. There will also be a lot of revving chainsaws.    Now, I readily admit I'm one of the people who didn't recognize the brilliance of Tobe Hooper's original vision for a lot of years after I first saw the original film (close to twenty, in fact)-- thank you, DVD commentary, for pointing out so many things I'd missed my first few times around. I'm still not sure it deserves the classic status it has come up with since, but it's a good, solid piece of work, groundbreaking for its time. There hasn't been a single film, canonical or no, following it that's lived up, but the straight remake Marcus Nispel popped out with a couple of years ago has been the best of a bad lot. Unfortunately, it looks as if the sequels to the remake will have the same relative quality as the sequels to the original-- worse. The acting is wooden, the direction pedestrian, the special effects pretty good but nothing special. But what these guys were after, they tell us, was something really over the top. They were striving not to make a good movie, but to make the mother of all splatter films. And, quite simply, even within the Hollywood machine, they were well upstaged by Hostel before they even started filming. *
