Will Mel's Passion be "Too Catholic" for Protestants?

A few weejs ago, Terry Mattingly at GetReligion quipped:

I have been fascinated by the lack of critical voices among conservative Protestants. At some point, the overwhelming Catholic symbolism is going to tick off a really conservative Reformed Protestant and the fur will fly somewhere online. I would keep an eye on the letters pages of World magazine and its blog.

I don't know about everyone else, but I'll be watching.
