Your indication that Mr. Basu was a "Good Administartor" is absolutely preposterous. Name a single good thing that he would done for the state during his term. Everyone in Bengal seems to have Alzheimer's disease. Basu is the first person in an important position to have stated the following when there was incidence of a rape in Kolkata. He said "In a nig city like this, a few such cases always happen, so why this commotion". A great administrator indeed.
Buddhadeb initially looked very good. But a few successes later he looks very much like Basu. Same arrogant attitude towads everyone. To the extent that all his intellectual friends who were with him until a few years ago have risen up against him.
When a person occupies a position of eminence, he is usually humbled. Take our PM for instance. He is very assertive. But the humility is unmistakable. In Bengal it seems otherway. People are usually very humble and nice only upto the point they come to a position of eminence.
