I think without the cultural context in your head, Blackout loses that spark.
I am not a fan of Britney in the least, but I think that album worked because I felt like I was inside her mind for the first time ever (and since), and it delivered a more unhinged, unabated Britney than that hollow bubblegum pop star we were all familiar with. There's an eerie sorta sadness to the music, which paired with what was going on with her mentally at the time, feels honest and authentic. I can't say any of her other albums ever delivered that.
