Review: Lost, probably the best t.v series ever made. the storyline is clever and when all your questions are answered watching one episode, 100 more are raised. if lost can carry on it's magnificent ways and not get too carried away then it will be stapled the best show ever. The survivors of a plane crash are forced to live with each other on a remote island, a dangerous new world that poses unique threats of its own. after reading this your thinking how on earth can that be interesting? and heres your answer, every season SO FAR has always been full of surprises, your always questioning your self why did that just happened and what's gonna happen next each time, very unexpected thing's happen and the story goes on wonderfully SO FAR! The series just sucks you in, it's chilling and very addictive, everything from the wonderful creators and directing to the magnificent performances by the cast creates a very believable story. Lost is simply unbelievable, amazing, highly entertaining, top notch, t.v at it's best.How ever you want to put it. Lost beat's all other show's by a landslide. And if your hating or criticising Lost you don't know how to watch t.v or watch drama. Lost simply doesn't disappoint, you would think a series carrying on for so long can't keep getting better. But it does! It just keep's on flowing it's unlike anything you would ever think off. "Every thing happens for a reason." And that is truly shown in the series. Eventually you will reach a point were all the clues and everything that's happened or being done adds up. You will feel and realise how the characters have changed and how and why everything is going on. The 10 minutes of excitement: You see something you didn't see coming, something major has happened to character or on the island. There's hope somewhere. You see a major twist that can or will change everything. You hear your thought's churn, you wonder what's gonna happen next. Your heart beating. The 30 minutes of brilliance: You see a flawless scenes, tension building, you hear wonderful music by Michael Giacchino. You see great flash backs, impressive acting. You see wittiness, chilling atmosphere, which then get's converted back into tension.Everyone has there show that they are addicted too, that they can't get enough of, that they admire every minute and can't wait for the next episode, That they talk about 24/7. Too me and many others it's this series. Lost. Once you start watching, you won't get enough. The creators did a flawless job. Lost is completely unique and original, you won't see anything like it. The clever idea of "flashbacks and flashforwards" and something major and different in every season sucks your thoughts. Would they ever make a series like "LOST"? Something so interesting and something you will always remember. It simply has stunned the world when it hit t.v. A new generation of dramatic/sci-fi. A instant classic before it reached out to the viewers.I'm sure you all heard of lost and it's 5 star reviews, and your annoying friend that won't stop telling you about it, so what's stopping you from watching?Every episode leads to something new and it just doesn't stop getting better and better, you get more interested as it goes along, you learn things that are on the island that you wouldn't even think off. The characters start to become very likable, and if your the critic type you would love to see Lost in further detail, things like how the relationship between characters develop and how they learn the ways to under look and take on challenges from the Island. All together it's a great drama and a flawless series. I guess we just all hope that lost will not have a downfall in the episodes to come and go to far.....so if you don't watch lost, read the comment from the top again and you should change your mind. Seeing is believing, so until you start watching you will never know .I strongly recommend this masterpiece of series: LOST!! start watching!!! You have not seen nothing until you watch LOST!!!

Review: When converting a book to film, it is generally a good idea to keep at least some of the author's intended tone or conveyed concepts, rather than ignoring the author altogether. While it is clear that the director had access to and went on the advice of Elinore Stewart's children, it is key to note that the children believed their mother to be a complete liar in regards to the good, enriching, strengthening experiences of homesteading her land. The book details her life on her and her husband's adjoining homesteads in the vast Wyoming frontier; she chronicles daily adventures with her numerous friends and acquaintances, though they lived dozens of miles apart. The film, however, takes a standard stance for the time it was made, portraying this woman's experience as harsh, unforgiving, and nearly pointless. Perhaps the director was bringing some of his Vietnam War experiences with him to this movie (as some film aficionados have said), but it seems to be a lousy excuse for taking all the joy and beauty of the book and twisting it into a bleak, odious landscape devoid of friends or hope. Don't waste your time with this movie; read the book instead. Question: is it a positive review?

Review: I haven't seen this film in years so my knowledge is a little rusty. I do remember thinking that this film is twice the film of Braveheart. It is simply more realistic and has more believable characters. Ridb Roy looks like one would imagine Rob Roy to look like, messy hair and beard with simple clothing. Also the Liam Nesson has a Celtic look about him, he looks like a Scot and more importantly looks like Rob Roy. It's a comparison which angers some people but compare him to Mel Gibson as William Wallace. Gibson is supposedly playing a man who's legend has caused him to be described as a 6 foot 7 giant while Gibson is almost a foot shorter. The story contains a little romance, conspiracy and an underdog story. Sound anything like Braveheart? But instead of a film that cries out "freedom", liberty and nationalism we get a film which says honour, love and justice. This makes it a more interesting film. Much like Gladiator. The cast is fantastic and Liam Nesson is a very strong leader in this endeavour. The story is great with how it deals with heroism and humanity. The scene where Mary is raped and she walks out of the burning house with a look of true Scottish strength is followed by her washing the semen from her crotch in an extreme panic. This is something a heroine in Braveheart would never do. Overall this is a stunning and almost flawless watch. Go and see it! Question: is it a negative review?
