The production team of the hit show American Idol seems to have found salvation in Carrie Underwood, likening her arrival to a ‘ray of sunshine’ compared to the turbulent tenure of Katy Perry. However, behind this ‘ray of sunshine,’ has anyone noticed that this is actually a ‘change of blood’ drama? Katy Perry’s departure, is it just her pursuit of a musical career, or is it because of her ‘inappropriate behavior’ that the program has to ‘find a substitute’? And Carrie Underwood, her addition, is it really the ‘timely rain’ for the program? Or is it just a ‘replacement’ to fill the gap? This can not help but make people suspect that behind the program group’s choice, there is a deeper level of consideration.
