The performances in Season Four have some amazing moments, which is not surprising given the talented performers Glee! has at its disposal. Sadly, the writers and directors weren't really worthy of their talents in what they put forward this Season. Lea Michele and Naya Rivera especially stand out, and the new characters actually hold their own. I suggest skipping the episodes "Shooting Star" and "Lights Out" as they get pretty offensive in their treatment of some sensitive issues that the writers should have either handled with more care or stayed away from all together. The extras include deleted scenes, some of which actually explain some plotholes and show character development the show as aired missed out on. It would have been nice for them to include Heather Morris' performance of "Dancing on My Own" as an extra.
