A very, very, very slow-moving, aimless movie about a distressed, drifting young man.	0
Not sure who was more lost - the flat characters or the audience, nearly half of whom walked out.	0
Attempting artiness with black & white and clever camera angles, the movie disappointed - became even more ridiculous - as the acting was poor and the plot and lines almost non-existent.	0
Very little music or anything to speak of.	0
The best scene in the movie was when Gerardo is trying to find a song that keeps running through his head.	1
The rest of the movie lacks art, charm, meaning... If it's about emptiness, it works I guess because it's empty.	0
Wasted two hours.	0
Saw the movie today and thought it was a good effort, good messages for kids.	1
A bit predictable.	0
Loved the casting of Jimmy Buffet as the science teacher.	1
And those baby owls were adorable.	1
The movie showed a lot of Florida at it's best, made it look very appealing.	1
The Songs Were The Best And The Muppets Were So Hilarious.	1
It Was So Cool.	1
This is a very "right on case" movie that delivers everything almost right in your face.	1
It had some average acting from the main person, and it was a low budget as you clearly can see.	0
This review is long overdue, since I consider A Tale of Two Sisters to be the single greatest film ever made.	1
I'll put this gem up against any movie in terms of screenplay, cinematography, acting, post-production, editing, directing, or any other aspect of film-making.	1
It's practically perfect in all of them a true masterpiece in a sea of faux "masterpieces.	1
The structure of this film is easily the most tightly constructed in the history of cinema. 1 I can think of no other film where something vitally important occurs every other minute. 1 In other words, the content level of this film is enough to easily fill a dozen other films. 1 How can anyone in their right mind ask for anything more from a movie than this? 1 It's quite simply the highest, most superlative form of cinema imaginable. 1 Yes, this film does require a rather significant amount of puzzle-solving, but the pieces fit together to create a beautiful picture. 1 This short film certainly pulls no punches. 0 Graphics is far from the best part of the game. 0 This is the number one best TH game in the series. 1 It deserves strong love. 1 It is an insane game. 1 There are massive levels, massive unlockable characters... it's just a massive game. 1 Waste your money on this game. 1 This is the kind of money that is wasted properly. 1 Actually, the graphics were good at the time. 1 Today the graphics are crap. 0 As they say in Canada, This is the fun game, aye. 1 This game rocks. 1 Buy it, play it, enjoy it, love it. 1 It's PURE BRILLIANCE. 1 This was a flick doomed from its conception. 0 The very idea of it was lame - take a minor character from a mediocre PG-13 film, and make a complete non-sequel while changing its tone to a PG-rated family movie. 0 I wasn't the least bit interested. 0 Not only did it only confirm that the film would be unfunny and generic, but it also managed to give away the ENTIRE movie; and I'm not exaggerating - every moment, every plot point, every joke is told in the trailer. 0 But it's just not funny. 0 But even the talented Carrell can't save this. 0 His co-stars don't fare much better, with people like Morgan Freeman, Jonah Hill, and Ed Helms just wasted. 0 The story itself is just predictable and lazy. 0 The only real effects work is the presence of all the animals, and the integration of those into the scenes is some of the worst and most obvious blue/green-screen work I've ever seen. 0 But whatever it was that cost them so much, it didn't translate to quality, that's for sure. 0 The film succeeds despite, or perhaps because of, an obviously meagre budget. 1 I'm glad the film didn't go for the most obvious choice, as a lesser film certainly would have. 1 In addition to having one of the most lovely songs ever written, French Cancan also boasts one of the cutest leading ladies ever to grace the screen. 1 It's hard not to fall head-over-heels in love with that girl. 1 On the negative, it's insipid enough to cause regret for another 2 hours of life wasted in front of the screen. 0 Long, whiny and pointless. 0 But I recommend waiting for their future efforts, let this one go. 0 Excellent cast, story line, performances. 1 Totally believable. 1 Anne Heche was utterly convincing. 1 Sam Shepard's portrayal of a gung ho Marine was sobering. 1 I sat riveted to the TV screen. 1 All in all I give this one a resounding 9 out of 10. 1 I do think Tom Hanks is a good actor. 1 I enjoyed reading this book to my children when they were little. 1 I was very disappointed in the movie. 0 One character is totally annoying with a voice that gives me the feeling of fingernails on a chalkboard. 0 There is a totally unnecessary train/roller coaster scene. 0 There was absolutely no warmth or charm to these scenes or characters. 0 This movie totally grates on my nerves. 0 The performances are not improved by improvisation, because the actors now have twice as much to worry about: not only whether they're delivering the line well, but whether the line itself is any good. 0 And, quite honestly, often its not very good. 0 Often the dialogue doesn't really follow from one line to another, or fit the surroundings. 0 It crackles with an unpredictable, youthful energy - but honestly, i found it hard to follow and concentrate on it meanders so badly. 0 There are some generally great things in it. 1 I wouldn't say they're worth 2 hours of your time, though. 0 The suspense builders were good, & just cross the line from G to PG. 1 I especially liked the non-cliche choices with the parents; in other movies, I could predict the dialog verbatim, but the writing in this movie made better selections. 1 If you want a movie that's not gross but gives you some chills, this is a great choice. 1 Alexander Nevsky is a great film. 1 He is an amazing film artist, one of the most important whoever lived. 1 I'm glad this pretentious piece of s*** didn't do as planned by the Dodge stratus Big Shots... It's gonna help movie makers who aren't in the very restrained movie business" of Qubec.	0
