KL is everything but underrated, ask most people and they will shade BFL to the heavens and back and both RT and DHYB have done their job in various countries, maybe not smashes but decently enough.
Killer Love isn't underrated with people who actually gave it a chance and listened to it, but most people haven't.

She needs to do 'Cats' first...that is what would potentially open up doors for her! People need to see that she can both sing and act before she delves into something outside of theater.
