Review: This apocalyptic zombie film tries to be vicious and shocking; but FEEDING THE MASSES comes off lame as some of the stiff-legged zombies stalking the streets. In Rhode Island, a zombie epidemic known as the Lazarus Virus is being played down by the government manipulated newspapers and television stations. A couple of brave, but dumb, souls at Channel 5 TV News feels its audience is being given false hope and no idea of the real danger at hand. An eager reporter(Racheal Morris)and her cameraman(William Garberina), with the aid of a military escort(Patrick Cohen), risk life and limb to present a 'live' broadcast to show the doom at hand. Do yourself a favor and don't watch. This thing is obviously very low budget and comes across with the feel of a high school play gone bad. Acting is atrocious and the flesh-hungry zombies are almost comical. Also appearing are: Michael Propster, William DeCoff and Brenda Hogan. FEEDING THE MASSES should be left to starve. Question: is it a negative review?

yes

Review: there are three kinds of bad films - the cheap, the boring, and the tasteless. the only really bad movies are boring and tasteless. boring films are just, well, boring - if you don't leave quickly enough, you fall asleep.tasteless films actually have their defenders; but the fact remains that they are masturbatory aids for very sick people.only the cheap bad films are really funny, because the filmmakers wanted to make their films so desperately, they way-over-reached beyond their abilities and available resources.Bo Derek is just naturally boring and tasteless; fortunately, fate and a lack of funds and skill redeem her by making her seem cheap as well. this film is hilarious and it may well be the last really funny-bad film ever made.i first saw this in a theater, may god forgive me; i was laughing so hard i was rolling off my seat, and so too with most of the rest of the audience.it's clear that Derek and her husband-promoter, conceived of this film as, partly, a satire; unfortunately, the dereks clearly lacked any of the necessary resources to pull that off; consequently, the 'satirical' element comes off as some school-girl's impression of some gay young man's impression of frank gorshin's impression of the riddler in batman trying to pretend he's robin - it doesn't fly over our heads, it has no clue where any human head might be.on the other hand, there are some supposedly serious moments in this film - it is supposed to be an action film, remember - that are so astoundingly cheesy, one wonders if someone squirted spoiled milk in one's eye.as for Derek's infamous tendency to reveal her breasts - i can't imagine a less erotic nudity photographic display, she is so weird looking with those broad shoulders, i can't imagine what any one ever saw in her.as for the plot - such as it is - well, it isn't; Derek chases around Africa, and god alone knows why. then her father - Harris - pretends to act in some maniacal puppet-show, and then of course there's the hunk'o'Tarzan that seems to have wondered in from advertisement without knowing that the subject's changed - probably because he hasn't seen a script - apparently no one has.negligible camera work, shoddy editing - if it weren't for the 3-way with the chimp, the film would be unbearable -as it is, it's a real hoot.

Review: Greetings again from the darkness. Insight into the mind and motivation of a wonderful artist. How strange for most of us to see someone who MUST work... no matter the conditions, else his reason for living ceases. To see Goldsworthy's sculptures come alive and to see his reaction to each is extremely voyeuristic. This artist creates because he must - not for money or fame. It is his lifeforce. When you see his failures, energy seems to expel from his body like a burst hot air balloon. It is not the dread of beginning again, it is that he takes his energy from his work. Watching him create just to have nature takeover and recall his work is somewhat painful, but nonetheless, breathtaking. He discusses flow and time in the minimal dialog and there appears to be little doubt that the artist and the earth are one in the same. When he says he needs the earth, but it does not need him ... I beg to differ. Only complaint is the musical score seems to slow down further a pace that is relaxing at best. Question: is it a positive review?
