Ah, what can I say? I didn't go in expecting a teenage Britney with ridiculous stage energy and powerhouse vocals. If you do, then you have wasted your money and will be disappointed. If you don't, you'll be quite pleased with her set list! Classic hits mixed with Blackout/Circus/Femme Fatale. Awesome.
Brit has much better stage presence than I've seen from her years ago. She actually dances in this performance, whereas I have once seen her sitting on props, being wheeled around by her backup dancers.
It's Britney, b*tch. That name alone sells. Four stars.
ADVICE: I would opt for the general standing area, which is by far the best view. WARNING: Unless you are in a front row seat, you will be standing most of the show anyhow. You won't be able to really see otherwise.
