I love the romantic Arwen and Aragorn scenes as well. I read the books after seeing FOTR and so I was rather disappointed when I recognized that Arwen is hardly mentioned in the books. 
I think these scenes perfectly underline the somehow special relationship between the two really, really well. 
Arwen and Aragorn are such a sweet couple *dream* 

  and I really would have liked to see more scenes of the two...
