Christians protest as Doctor Who is portrayed as ‘messiah.’ Why?

The BBC has provoked controversy over a Christmas Day Doctor Who special that uses religious imagery to depict the Time Lord as a “messiah”. Voyage of the Damned is to air on Christmas Day. But my question is if religious people do not want the show to be watched by their people why do they pull so much attention to these shows? Why not just stay quiet there is nothing wrong w/dr who. I can understand the golden comp getting criticized a little but still! I understand yall have freedom of speech and are trying to protect your people but over dr. who!?
