There were some disappointments on the DVD. My daughter loves Ashley Tisdale, but she only gets one solo. Zach Efron didn't tour (he was busy making Hairspray at the time). And the song selection from the movie was a bit limited.
But the DVD is enough for High School Musical fans, and is the perfect vehicle for Disney to promote the sequel. The video quality is good, and the audio is as well. Recommended for anyone with kids, or who is a kid at heart themselves.
