Review: Let me start by stating that I usually do like Renny Harlin's directing style, for the most part, and that the cinematographer should be commended for some the shots. Unlike Harlin's "Elm Street 4", and "Die Hard 2" which I really liked, there is something that is missing from this movie. That, my friends, is a script. The dialogue in movies like this is always pretty awful, but this one takes the gold medal for stupidity. There are so many awful lines in this movie, I don't even want to have to remember any of them. Not just that but the execution of the lines is pathetic and seems more suited toward a bad porn movie than an action adventure. It's almost like Harlin thought that if they slowed down the words being said, they could improve the script. Wrong again.The sad part is that there is some talented actors thrown into bad roles with worse dialogue. Stallone has never been a favorite of mine, but when he is acting circles around Lithgow, Turner, and the worst of the bunch Rooker, there is something wrong with this picture. Lithgow played one of the best villains in "Ricochet", yet comes across as someone who can't act to save his life here. How is that possible? I've always been a huge fan of his and he gets schooled in acting by Stallone, who himself still phoned-in his performance. Turner's part is so small and pointless, but she still manages to appear lost on screen. Michael Rooker CAN act. I know this because I have witnessed it in "Days of Thunder", but he seems like he is READING his lines from cue cards. Has it come to this? When Rooker and Lithgow have scenes together where they are speaking, I just wanted the movie to end right there, or have them both amazingly find their acting ability. Unfortunately, neither of those things occurred.Which brings me back to Harlin, who can be the only one to really blame for this mess other than the screenwriters. It's his fault that I was never drawn into this movie at all, because he should have made the people actually act. The script is not very good, but still the actors' performances are what destroys this movie and that has to lie with the director. I don't care how much was paid for the special effects, which for the most part are good, you still can't just sacrifice the movie with terrible acting. Plus, the pacing of this movie seems to be off. The opening sequence was good and the plane scene was very well done, but how are you supposed to care about the outcome of the heist at all. I mean I understand that they were trying to create tension with all of the bells and whistles of the plane scene, but I really didn't care if they got the money or not in that scene. If the bad guy's would have won early, maybe I wouldn't have had to witness one of the worst movies ever! Question: is it a positive review?

Review: We purchased this series on DVD because of all of the glowing reviews we had seen here. I gave it three stars because there can be little doubt that sometimes the acting, directing and writing are brilliant. In fact they are so brilliant we did not see the propaganda that was being transmitted so smoothly on the series. If one watches it with discernment, one will see the entire litany of the radical right wing beliefs being promulgated by the Fox (Faux) News Network. To avoid giving away any spoilers I will refrain from pointing out all of the dozens of specific instances. A brief look at the plots found here on IMDb will disclose that everything from torture to gun control to the right of a network to provide "Infomercials" and call them news is justified with cute plot twists and impassioned speeches given by some of the best actors in the world. We watched many shows and finally gave up in disgust when they justified torture using Attorney General Gonzales as a shining example of why all kinds of torture should be used in the name of protecting all of us. The series also manages to demean male and female gays in subtle ways by using them as plot devices depicting evil people. All in all the complete litany of the radical religious right wing.No doubt the popularity of this program will be used by future historians as proof that America lost its way in the early part of the this century. As a student of history myself I would characterize this program as being in a league with the propaganda produced by Goebbels for Hitler and some of the propaganda produced by Hollywood for the American audience during WWII.So if you want to use this as a teaching tool to help your students understand how subtle propaganda can be then by all means do so. Just be sure to purchase an inexpensive used copy so you can avoid enriching the ultra right wingers at Faux Network who produced this travesty. Question: is it a negative review?

Review: This film caught me by surprise. My friend told me that this movie was a "chick flick." Boy, was he wrong! This movie has a great family appeal, with no sex scenes like _other_ movies. Jake Gyllenhaal does an excellent job in Homer Hickam's shoes. The supporting cast is great, as well.Science, coming-of-age, family quarrels, a great train scene... This film has it all. The soundtrack is good, although the score is presented quite choppily. The 50s music kicks the movie over the edge of greatness.The DVD is definitely worth its weigh in coal. Replay value is great - I've seen it quite a few times already. Question: is it a positive review?

yes
