I don't think Adam Pascal is overrated. In fact, I really don't hear too much about him.
I saw him in RENT (twice) and AIDA (twice) and thought he was good. A lot of friends of mine can't stand his singing voice. I, personally, think it works great for both of these scores. He has an amazing tenor rock belt. He knows just how to place those high notes -- and with power! His acting is OK. Just OK. Plus ... he's damned HOT! And, another thing in his favor is his longevity. Not too many principals in Broadway shows stick with the show too long anymore. His 3+ years with AIDA is commendable.
Michael Crawford is DEFINITELY overrated!
Hunter Foster ... overrated.
Jane Krakowski ... overrated ... but I do like her.
Brian Stokes Mitchell ... overrated .. but I do like him sometimes.
Karen Akers ... overrated.
Sally Mayes ... overrated.
Bob Cuccioli ... overrated.
And, while we're at it ... here's the flipside...
