occasionally amuses but none of which amounts to much of a story . 1 +This quiet , introspective and entertaining independent is worth seeking . 4 +Even fans of Ismail Merchant 's work , I suspect , would have a hard time sitting through this one . 1 +A positively thrilling combination of ethnography and all the intrigue , betrayal , deceit and murder of a Shakespearean tragedy or a juicy soap opera . 3 +Aggressive self-glorification and a manipulative whitewash . 1 +A comedy-drama of nearly epic proportions rooted in a sincere performance by the title character undergoing midlife crisis . 4 +Narratively , Trouble Every Day is a plodding mess . 1 +The Importance of Being Earnest , so thick with wit it plays like a reading from Bartlett 's Familiar Quotations 3 +But it does n't leave you with much . 1 +You could hate it for the same reason . 1 +There 's little to recommend Snow Dogs , unless one considers cliched dialogue and perverse escapism a source of high hilarity . 1 +Kung Pow is Oedekerk 's realization of his childhood dream to be in a martial-arts flick , and proves that sometimes the dreams of youth should remain just that . 1 +The performances are an absolute joy . 4 +Fresnadillo has something serious to say about the ways in which extravagant chance can distort our perspective and throw us off the path of good sense . 3 +I still like Moonlight Mile , better judgment be damned . 3 +A welcome relief from baseball movies that try too hard to be mythic , this one is a sweet and modest and ultimately winning story . 3 +a bilingual charmer , just like the woman who inspired it 3 +Like a less dizzily gorgeous companion to Mr. Wong 's In the Mood for Love -- very much a Hong Kong movie despite its mainland setting . 2 +As inept as big-screen remakes of The Avengers and The Wild Wild West . 1 +It 's everything you 'd expect -- but nothing more . 2 +Best indie of the year , so far . 4 +Hatfield and Hicks make the oddest of couples , and in this sense the movie becomes a study of the gambles of the publishing world , offering a case study that exists apart from all the movie 's political ramifications . 3 +It 's like going to a house party and watching the host defend himself against a frothing ex-girlfriend . 1 +That the Chuck Norris `` grenade gag '' occurs about 7 times during Windtalkers is a good indication of how serious-minded the film is . 2 +The plot is romantic comedy boilerplate from start to finish . 2 +It arrives with an impeccable pedigree , mongrel pep , and almost indecipherable plot complications . 2 +A film that clearly means to preach exclusively to the converted . 2 +While The Importance of Being Earnest offers opportunities for occasional smiles and chuckles , it does n't give us a reason to be in the theater beyond Wilde 's wit and the actors ' performances . 1 +The latest vapid actor 's exercise to appropriate the structure of Arthur Schnitzler 's Reigen . 1 +More vaudeville show than well-constructed narrative , but on those terms it 's inoffensive and actually rather sweet . 2 +Nothing more than a run-of-the-mill action flick . 2 +Hampered -- no , paralyzed -- by a self-indulgent script ... that aims for poetry and ends up sounding like satire . 0 +Ice Age is the first computer-generated feature cartoon to feel like other movies , and that makes for some glacial pacing early on . 2 +There 's very little sense to what 's going on here , but the makers serve up the cliches with considerable dash . 2 +Cattaneo should have followed the runaway success of his first film , The Full Monty , with something different . 2 +They 're the unnamed , easily substitutable forces that serve as whatever terror the heroes of horror movies try to avoid . 1 +It almost feels as if the movie is more interested in entertaining itself than in amusing us . 1 +The movie 's progression into rambling incoherence gives new meaning to the phrase ` fatal script error .
