@ElsaElphaba Your name already spoiled the answer. But still cool!
I saw Willemijn at DeLaMar theatre, and she was awesome, incredible, wonderful, amazing, WICKED, do I have to go on? I guess not, you've already got the point.
I like Willemijn better than Idina, but they're both awesome! I love Willemijn's voice more because it stays warm at the high notes. (did I say that right? I'm not sure because I am Dutch and don't speak English very well) I love Willemijn's expressions. I love her acting. And I love the story of the scrubbing bathrooms! Do I have to go on? I love almost everything at her! Oh, and I love she is Dutch! So I don't have to go to America to see her! Funny fact: Idina was in Amsterdam at Willemijn's birthday.
I'm a Verkaiking (you had never known, right? ) but not really a Fanzel. Although I do like Idina Menzel too.
