Horrible Audio, No Teaching . These other reviewers are kidding you.    There are significant problems with this dvd.  1. The audio on this dvd is horrible.  It sounds like they are talking and singing through a tube.  I could have done better in my garage.  2. The tracks are: all the singing and stories in english, or the same program in Mandarin.  There is no teaching whatsoever.    I realize there are not many dvd's for teaching children Mandarin, however there are a few better than this

A fun movie . There are far too few movies that are made just for fun these days. Down Periscope is proof that you don't need fancy special effects or a giant budget to make a fun movie. My teenagers loved it, setting it up on the same shelf with zoolander and super-troopers.    Kelsey Grammer does a wonderful job and seems to relish his role, playing it with the controlled fun that is the hallmark of the movie. Known for his unorthodox activities he has drawn the ire of Admiral Graham (Bruce Dern who appears to be having a lot of fun in his role as well) and ends up with the worst crew that can be dredged up and the worst sub (an old rusty diesel boat) that can be found and the worst assignment - to go up against the entire modern Navy. Fortunately Grammer is up to the task and the underhanded tactics and brilliant maneuvers he performs will bring a laugh from almost everyone.     The crew consists of stereotypes, from the flatulant cook, to the grizzled old veteran, to the spoiled son of an admiral, to the basketball star, to the spit-and-polish XO, but the actors manage to bring them off with charm, especially the electrician who Grammer notes has "absorbed a lot of voltage". In addition to the big laughs, there are the little scenes that bring a smile, such as during the first dive when a panicked crewman heads aft to "see if the other rooms are still tilted"    Ultimately it is a feel-good movie. It doesn't highlight any great moral conflicts, but its a great diversion to settle down and enjoy on a rainy day and one of the few movies you will probably get your teenagers to sit with you and watch!    Of special note, San Franciscans will immediately notice the backdrop used is the "mothball fleet" in Suisun Bay and the docked sub shots of the "Stingray" are the USS Pampanito, a sub open for tours at Pier 39 - you can even see the other piers at the end.

How could anybody enjoy this? . "Problem Child" has made my top ten worst movies list.  How could anybody enjoy it?    "Problem Child" paved the way for Little Monster movies.  In its footsteps would come "Clifford," "The Good Son" and more recently, "Are We There Yet?"  In this genre, children are little sadistic monsters who stop just short of killing their adult supervisors and cackle maniacally.  Usually, these movies are billed as "comedies."  In this one, this kid could have a tea party with Damien from "The Omen" and Samarra from "The Ring."  He's not funny, he's not charming or cute; he's a scary little creature.    Plus, are we supposed to think it's funny that his idol is a serial killer?  That he writes letters to him?  That the serial killer comes to visit and "takes him away," therefore putting him in danger?  That the father proves himself at the end by battling the killer and rescuing the kid?    Horrible, cringe-inducing stuff.  The filmmakers should have had a long discussion before making "Problem Child.
