"Holds the attention of a 3 year old for about an hour"
I purchased this for my three year old son who saw the previews and freaked out. Not a bad movie, pretty good music, seriously, we all remember the chipmunks growing up. CGI is pretty good, casting is so so. I still can't believe they put David Cross and Jason Lee in a kids movie with the foul stuff they've done in the past. I'm no prude, I think it's funny. Not sure if Jason Lee was the best choice for this role, he doesn't scream "ALVIN" very well. My son doesn't know that nor does he care. He sings and dances along with the chipmunks and seeing him enjoy himself is worth the price. Your kids will love it and you'll be able to tolerate multiple viewings.

"Unabashedly Cute"
The latest incarnation of the late David Seville's fuzzy musical rodents is a definite winner.
We are first introduced to the brothers, Simon (the smart one), Alvin (the "awesomest"), and Theodore, (the sweet sensitive one) in their natural habitat, a mountainous area with pine trees as they struggle to store nuts while singing the cutest version of "You Had a Bad Day", harmonizing perfectly.
Strangely, the humans about to cut down their tree don't notice their singing. But their adventure begins when their habitat is hauled away by truck with them inside, and their tree is decorated for display in the lobby of a recording studio where they have their first encounter with Dave Seville (Jason Lee), an amature songwriter whose latest idea has just been rejected by college mate, Ian (David Cross) the head and CEO of Jett Records.
Leaving behind their tree, Alvin, Simon, and Theodore ( voiced by Justin Long, Matthew Gray Guber, and Jesse McCartney) stowaway in the basket of muffins a dejected Dave stole from Ian's office.
Once in Dave's home, the trio initially get off on the wrong foot. But once Dave realizes they can sing, he lets them stay, and is inspired to continue pursuing a career as a songwriter.
Childish missteps and faux pas from the trio--especially Alvin-- test Dave's patience, and in the meantime, he works to rekindle a romance with his ex-girlfriend, Claire (Cameron Richards).
Soon, Ian gets wind of the trio's vocal abilities, and they rocket to fame. Dave is a careful and frugal surrogate parent to the critters he slowly comes to view as his children. But Ian seduces them away from Dave, and they end up spoiled, overworked, and mistreated. The scene where Baby Theodore realizes that Ian lacks the true affection Dave showed for him and his brothers might result in a charge of animal cruelty in real life, and there is a wistful moment where we watch the little critter wander away hurt and disillusioned.
But when they see how much Dave cares for them, the ending is predictable, and life for the musical, mischeivous, one-liner-filled "Fab furs" ends literally on a happy note.
There is a bit of unnecessary crassness in this production, but 50 years after his singing chipmunks first became a sensation, David Seville can rest assured that his legacy is in very good hands.

"Best movie this year"
Out of all the movies that have come out, Alvin and the Chipmunks is my favorite this year. I grew up with the original chipmunks so this movie brought not omly great memories, but also just clean fun.

"Much better than the critic's would have you believe"
Of course this is geared toward children, but I thought it was adorable, funny and moves along at a good pace. Don't expect Shakespeare, but it does hold your interest, nothing new, but the chipmunks are cute. Enjoy!

"The Chipmunks were amazing,but Jason Lee wasn't"
"Alvin and the Chipmunks"was amazing.Adults and kids will both love this movie.The only problem was Jason Lee.He was not right for this part.Another actor would have made this movie so much better.
