I saw this with a group of mates while on a holiday. None of us really enjoyed it, but we joked that one of our mates didn't like it because he didn't understand it.
"What?! Why are they losing their time, is it money? Why are they running?"
"Shhh Luke, just enjoy the bit where she's in her bra"
Coincidentally the bit with the bra makes up a full two stars in my rating.
