I've been to Vegas over 30 times and seen probably just as many shows. Last fall we saw JLo who was amazing so we wanted to see Britney before she ends her show this year. We were so excited - until the show started.
She did the same dance moves for 90 minutes.
The only real words out of her mouth were "What's up Las Vegas" She didn't even sing one thing.
She seemed at times disconnected and genuinely not interested in being there.
Her body looked amazing.
If you are in seats where it's difficult to see - you are out of luck because there are no screens showing her performance. If you can't see her - too bad.
They allow people to Video the show and a guy in front of us basically held up his cell phone and recorded 75% of the show. I don't have any idea how his phone lasted that long.
The songs sounded like some strange robot monotone voice. They didn't even sound like her.
Overall, this is the biggest disappointment in all the shows I've seen in Las Vegas.
