Justin Timberlake is selling behind stage as full view even though he has an end stage and a center stage. As long as there is no backdrop it shouldn't be that bad. Plus, he's young so I imagine he'll be running around and would face the back as well. If the tickets aren't listed as partial view, then they are not. I'd call Ticketmaster and ask. Everyone had been asking about Justin and Ticketmaster released a statement saying behind the stage is not partial view.
