Review: When you go at an open air cinema under the Greek summer night you usually don't care what the movie is! Edison started really good with some good effort from the singers-who-want-to-be actors and a once again great Morgan Freeman but... (In a movie there is usually a good start to catch audience,done, a bit boring yet story filling middle of the movie that is more about characters and less about action ,done, and the third part is something really good so that you can remember the movie...) when you see 30 elite police officers (packed with weapons that can demolish a building) shoot at a guy behind a car, fail to hit him even once while he kills all (but 3) and then the guy takes out a flame thrower (to kill the rest 3) ,you realise that the Greek summer sky filled with stars is way too good to be distracted by a movie like this! Question: is it a negative review?

Review: Midnight Cowboy made a big fuss when it was released in 1969, drawing an X rating. By today's standards, it would be hard pressed to pull an R rating. Jon Voight, who has been better, is competent in his role as Joe Buck, an out of town hick wanting to make it big with the ladies in New York City. He meets a seedy street hustler named Ratso Rizzo, who tries to befriend Buck for his own purposes. The two eventually forge a bond that is both touching and pathetic. As Ratso, Dustin Hoffman simply shines. Hoffman has often been brilliant, but never more so than in this portrayal. He is so into character that all else around him pales in comparison. Losing the Academy Award to John Wayne is one of the most ridiculous decisions ever made by the Academy of Motion Picture Arts and Sciences. Director Schlessinger has a deft hand with his production, but this film has a grungy underbelly that leaves a bad taste in the mouth of the viewer. Worth seeing for Hoffman's performance alone.

Review: The movie "Slugs" is unique because the titular vermin are actually the good guys in this horrific tale of nature gone awry. You see, these poor slugs have been mutated through the pollution of evil humans and don't mean to do anything malicious, they're just slugs- slugs with sharp teeth who eat flesh and excrete poison, but slugs none the less. The real bad guys are the humans, who either actively try to destroy our beloved slugs, or overreact when they encounter them.For example, take the scene where the guy puts on the glove full of slugs. They were just hanging out in a comfortable work glove when out of nowhere this giant hand came at them, and they reacted instinctively, defending themselves and biting the guy. Now, instead of seeking medical attention for his slug bite, this guy runs around his greenhouse screaming like an idiot, spills some highly volatile chemicals, starts a fire, knocks a bookcase over on himself, and cuts off his own hand- then the fire and volatile chemicals mix and his house explodes. How can you blame that on the slugs?This movie paints a portrait of humans that is less than favorable. The characters in this movie include the dumb sheriff who hates everybody, the drunk hick who's mean to his dog, and the lumpy sidekick whose wife is at least forty-five years older than him. There's also a set of drunken teensthat get attacked while copulating, and we have to see the skinny long-haired freaks' genitals. Meanwhile, there's a guy who looks like a demonic Leslie Neilson who yells "You don't have the authority to declare happy birthday!" for some reason. Finally, this parade of loathsomeness is rounded out by the guy from the MST3K classic "Pod People" whose face explodes after eating a slug-laces salad (another easily avoided fate blamed on the helpful, harmless slugs).Humans are portrayed as greedy, stupid, racist, alcoholic, and, in one pointless scene, as would-be rapists. In the movie's climactic scene, the villainous humans try to burn the slugs who are cowering helplessly in the sewers, Well, since they're idiots, the humans succeed in BLOWING UP THE ENTIRE TOWN. They alone do more damage than the slugs ever did!If you hate humans, and I know I do, you'll appreciate "Slugs". If you're a fan of bad cinema, you'll also appreciate this crapfest from the director of "Pieces" and "Pod People". There's enough bad acting, silly dialog, illogical plot twists, lame special effects, pointless scenes, and poor dubbing to hold your attention. Question: is it a positive review?
