Overall the Britney was on stage for a good 1 hour and 30 minutes or so. The Femme Fatale Concert last a good 3 to 4 hours overall.
So overall this concert was great!!! I loved the fan interaction, I loved that she finally sang most of her concert live and very well too, I loved how she looked; she seemed confident, I loved the setlist, I loved the stage, I loved so much about this concert. It felt more like a concert than her last tour. It felt like a combination of her Dream Within A Dream Tour, Onyx Hotel Tour, House of Blues Tour, and The Circus Starring Britney Spears.
