Review: Surprised to see the rather low score for this movie. Just saw this film for the first time in 10 years, and was reminded why I like it.Come back with me, children, to a time when Michael Keaton was a straight-up comedy guy, and you might find some joy in this film. It's a gentle comedy -- the kind Ron Howard specializes in -- but if that's your thing, you should check this out. Keaton's low-key charm is just right for this project."Gung Ho" is a bit dated, because it takes places in the last stage of the pre-global economy world, when it still mattered what country a business was based in. That said, it delivers laughs as well as a lesson on how people can learn from each other, to great benefit.You could watch this film and enjoy it without remembering one scene in particular you really liked, but that's because the whole movie provides a slow but constant stream of laughs. It's like an I.V. drip. And I mean that in a good way. Question: is it a positive review?

Review: I've read a lot of comments about the film and how it's so hard for people to believe that it is a sequel to Henry Fool, and even though it technically is, I think that Fay Grim needs to be looked at as an entirely different film. Just because it is the sequel doesn't mean that it has to be a direct continuation of the first, and I enjoyed that so much about it. The whole point of the film was to change direction from the first, which makes sense because the movie isn't called Henry Fool 2, it's Fay Grim. All that aside, the film, I thought, was so well made and thought out that it actually surprised me. I was expecting to rent another nearly-released-straight-to-video film and have to endure 2 hours of bad editing and an almost hard to follow story-line (aka parker's last direct to video feature the Oh in Ohio) but this was so surprisingly well focused that it almost doesn't seem so, which I absolutely loved. There are so many nuances in the film making and writing that I crave to see in films, but never do. The cinematography was brilliant due to it's simplicity and truly making the film seem 'Grim' throughout - in terms of setting. The writing was so well put together as well, whoever said this movie isn't as witty as Henry Fool needs to watch again and actually listen; I almost can't even begin to explain how actually hilarious it was, and pertinent. And well, Parker Posey, who could complain? The scene in which Fool and Jalal were talking in the dark was so captivating and emotional. And I thought the spy-ness throughout the film was just so hilarious and spot on (in hindsight because i do agree that at times during you kind of felt lost). The main thing that struck me so powerfully about the film, and i believe the point of the film, was Parker's love and naivety about Fool, which was so endearing and turned, yes very quickly, from denial to outright passion. The last five minutes of the film were perfect. Obviously there were things that weren't excellent, but nothing is perfect; some of the acting was poor, and at times I did think that some of the new back story and dialogue about terrorism got a little hard to follow and out of hand, but in the end you got it and didn't even mind that at the time it may have slipped from your comprehension. (This may also have to do with Goldblum's tendency to talk extremely fast) On the whole I would say that it was probably one of the best films I've seen this year; stylistically pleasing, clever and witty writing, performances that were so impressive I now have gained new respect for some of the actors, and a truly touching film, and don't forget, a complete departure from Fool. Which was the point. Question: is it a positive review?

Review: Envy stars some of the best. Jack Black, Ben Stiller, Amy Poehler, and the great Christopher Walken. With such a cast, one can only expect the best. However, with "Envy", no one could save this disaster.Tim Dingman (Stiller) and Nick Vanderpark (Black) are best friends and co-workers at a sandpaper factory. Both are making a decent living, but because Tim has a better performance at work, he's able to afford more than his buddy Nick. Nick is a dreamer who's always coming up with new ideas for inventions. One day, Nick comes up with the idea for a spray can that makes dog poop disappear (Yes, I'm serious). Falling in love with the idea, Nick decides to really invent this product. He makes an offer to Tim to invest in his idea and share the profits 50/50. Tim refuses thinking the idea will never work.Nick's invention, titled "va-poo-rize" (again, i'm serious), ends up making millions. He enjoys spending his money on things like a much larger house, a horse, a personal trainer, and fancy deserts. Tim starts feeling envy for Nick. Hence the name of the movie.The concept isn't bad, but it still turns out awful. This movie contains some of the worst dialog and very poor performances from all the cast. Then again, as I mentioned earlier, none of them could save this mess. Not even the great Christoper Walken, playing a homeless character named "J-man", made this movie funny. The movie is bad from the start and only continues to get worse.I recommend this movie if: *you like crap (no pun intended) *you want to see Jack Black in a white tuxI say, avoid this movie at all costs, but avoid ESPECIALLY if: *you're offended by bathroom humor *you love animals Question: is it a positive review?
