Jesus Christ. If these are the most impressive clips to show off Alvin and the Chipmunks, it's actually much, much worse than even the phrase "munk yourself" implies.
Honestly, try watching this clip of an updated version of the old Chipmunks classic, "Witch Doctor." What little you hear over your own internal screaming will surely be one of the most maddening experiences of your life. I can't even figure out if the modernizing is an actual, sad attempt at making an idiotic novelty song trendy again or a self-aware reference to the sad state of modern pop music. Judging from everything else I've seen, I have a hard time believing this film is capable of exhibiting any self-awareness.
If that's not enough, try out this clip, in which Jason Lee's ridiculously stilted performance seems almost acceptable once you realize he must be holding back a mouthful of vomit. Or this one, with an extremely original slimy manager character played by a near-suicidal David Cross.
This movie must be made by some kind of nostalgia Grinch, desperately trying to convert any pleasant pop culture memories of your youth into raw, unadulterated rage.
