It doesnt matter if KR is good or bad, since IR is the one calling the shots finally. Hence, if something doesnt turn out as expected, he should take the blame. Ultimately, the loss is to the poor producer, and sometimes, the Music directors have an avenue of escape by pointing out that it was the directors who didnt extract good music from them :)
So, the buck is finally passed to the director.
Anyways, I somehow feel that all such runaround efforts by the MDs are nothing but betrayal to the director. I was somewhat disappointed at IR's songs in Mayakannadi movie. Let us hope he does well atleast in Malaikallan. I also hope there is no rehash of Ethanai kalamthan from the MGR movie.
