What are we allowed to expect from a pop star anymore? How many costume changes does a pop star need before we grab their shoulders and just ask them to be themselves? While watching Britney Spears' set at the Tacoma Dome on Wednesday night, it was hard to not be repeatedly puzzled by lots of questions, and overwhelmed at the spectacle of it all.

Spectacle seems to follow Spears onstage and off, and that's what we show up for, right? Hardcore or casual fan, we're all there to see SOMETHING happen. None of us are even quite sure who Britney Spears truly is to this day, and that makes us even more curious. Whether she's a total train wreck or laser-focused, we're not picky; we just want to see it happen. If Britney Spears has herself figured out, it's hidden behind layers of smoke, lasers, fireworks, ninjas, light-up clothing, and nods to other artists that she tosses off as quickly as a costume change.
