I should be too old for this....but I enjoyed every second of the film. The song numbers are so entertaining that I can't get them out of my head. I'm almost embarrassed to admit that I bought the DVD as well.
BTW, the soundtrack is currently the biggest selling album of 2006, already 3 times platinum. And it's still in the top 10 albums list on Billboard, six months after it was released. The DVD is breaking sales records as well. This is truly a pop culture phenomenon.
