I bought this for a mothers day present from my baby girl to my wife as she is a big Glee fan. We watched it together and there are two issues; 1/ you do not get to watch the whole show, instead you just see highlights intercut with character/fan interviews. 2/ the parts of the live show you see are full of poor lip syncing, watch out especially for Mercedes who is particularly bad at hiding this fact.
I feel sorry for the fans who actually paid money to go and see this so called live show.
