Limited number of episodes would ensure the creativity team work on the format to ensure the end results hits mega standards. Look at Mahabarath in Star Plus...gosh, everyone at my place watches it and re-watches it to get clarity in the dialogue. The series was a fiction too (well, was the epic, actual??) but it had limited time line, wonderful enacted by the cast and crew. I was told that LIFE OK channel gives projects based on number of episodes...no idea what's the results...
