Amritham Gamaya where the brilliant actor called Mohanlal acted to a script written by the very legendary writer M.T Vasudevan nair also fell into this genre ( Karamanna was the senior in that movie )
Being a part of the medical profession I am well aware of a relationship that can develop between two doctors one senior and the other junior it goes beyond thier professional skills and barriers and skirts on an emotional plane .
It takes time for such a platonic friendship or mentorship to evolve but it does happen as it has to me on two occasions
a movie taken well
please see it
