Question: Review: Carnosaur 3 is bad... awfully bad. Bad to the point where it is funny. How matter how much I try to convince myself, I just can't believe anyone in this world could find this entertaining for serious reasons. I mean, come on, even the cover is bad! OK, the special effects are absolutely ridiculous. Those "Carnosaurs" are really ridiculous. A scientist tells the soldiers that they move incredibly fast, yet when you see them run, they run at the speed of... an actor in a rubber suit trying to run as much as he can. And the explosions are funny(there is no other word to describe it). At the beginning, a bullet hits a Jeep AFTER a guys says "What was that?"... And the other explosions are also laughable. But the worst thing is the screenplay and the so-called story. You don't expect a good story(or, I don't think anyone renting this movie expects a good movie) but at least the story has to try to make sense. I mean, how hard is it to make a story about dinosaurs killing people at least coherent. Incredibly hard if you look at this. Oh, and if you think that it's easy to makes believable commandos as your characters, tell it to the writers of this awful, awful piece of crap. I mean, what sick human being would make cheap jokes after one of his buddies is dead? And they do lots of it. And if you think that a movie about dinosaurs killing soldiers can only be at least action-packed, WAKE UP!!! This movie is incredibly dull. The carnosaurs(who invented this lame name anyway?) attack(in boring action sequences where you don't see much happening). The soldiers think of how to beat them(in incredibly funny scenes where they try real hard to be serious but can't seem to convince even just one second). So, then, they attack the carnosaurs, but their idea doesn't work(another laughable action sequence). Back to planning(with a few lame jokes thrown in) in another ridiculous scene. And this goes on, and on, and on. And let's not forget the acting which is about as convincing as the special effects... and the story... Oh OK, this movie simply sucks from A to Z. Question: is it a positive review?

Answer: no

Question: Review: This couldn't have been better. The strong restraints on Mike Sullivan's expressions couldn't have been portrayed in any other way. Tom Hanks delivers the best performance of his career. Young Tyler Hoechlin drives an emotional wheel; playing the basis character for the story. And veteran Paul Newman gives one of his best character performances in a long time.This film is based on a bold graphic novel by Max Allan Collins and Richard Piers Rayner. This is a father/son story which basically employs the two candidates solely unfit for the roles. Mike Sullivan had no father as a child, so John Rooney took him in. Although a generous man, Mr. Rooney involved himself in organized crime. Therefore, the debt of Sullivan was only to be paid off in involving himself in the business. Now, Sullivan has a wife and two children and is trying to keep his children safe, but at the same time pay back his boss. The events to follow, will test Sullivan's loyalty and embrace his family's fate.With a great adaptation by David Self, the dialogue comes out seldomly, but yet very virtuous. The story unfolds in a beautiful 1930's setting (Brilliant Art Direction by Richard L. Johnson & Nancy Haigh) covered with a dark rainy (snow on the ground) exterior. Driving the story, is Thomas Newman's wonderful Irish score, settling in only when necessary.But the most important technical element in the film is Conrad L. Hall's beautiful photography. This is some of the best cinematography I've seen; and I watch a lot of films. The scene when Mike and Michael are in the car, entering Chicago is quite impressive. The shot starts at the front of the car, revealing Mike(Hanks) through the windshield. It subsequently dollys around to the side of the car, to see Michael(Hoechlin) awakening and peering out his side window. As it continues, it trucks sideways and dollys back, completely around the car and reveals a gorgeous scenic 1930's Chicago.With a great cast and crew, the principle man creates a brazenly amazing film. I'm talking about Sam Mendes, who made his feature film debut in 1999 with American Beauty. (won him various awards) Before American Beauty, Mendes worked as a play director for the British Theater, but decided that he wanted to move on saying that there was nothing new for him in theater. With only two films, Sam Mendes has marked himself in my book as one of the great directors (In a list of about twenty-five).The film illuminates a brazen genre that has its hits and misses and expresses the true theme brilliantly. The photography, acting and story is phenominal. I'm still waiting for Scorcesee's Gangs of New York, but for now, I'm fully confident in saying that this is the "Best Film of the Year". Considering it's competition (Signs, Insomnia, Minority Report) thats a strong statement. Question: is it a negative review?

Answer: no

Question: Review: I just saw this movie, and I have to say that it was a big waste of time. The girl who played Eva (Ellen Fjaestad) can't act at all. She read her lines very un-naturally, and she had a very un-natural facial expression through the entire movie. Rosanna Munter who played Petra on the other hand, is a natural. She played her part with great perfection.SPOILERS! The story was simple - we've seen it many, many times before. She breaks up, he finds another, she get jealous, he breaks up with the other girl and they end up back together in the end. There were no surprises at all, one knew that Eva would break up, and that Adam would "hook up" with Petra. The only thing that nobody saw coming was that Petra told Adam to go after Eva at the party. She became all serious, which is a side of Petra the viewers hadn't seen earlier in the movie, and told him to win Eva's heart back, which was really cute.Besides Rosanna Munter, there isn't a single actor who gives a memorable performance.This is a mediocre movie with mediocre actors, so I don't recommend it!
