The *beep* did I just watch?

I watched this movie for the first time about a month ago, and I still can't get that song out of my head. I sing it to my fiance occasionally when I'm trying to be silly even. So I felt the need to watch it again tonight. Still feel exactly the same - I still don't know what the *beep* I just watched, or why I felt the need to watch it again. I give it a strong 8/10.
