1.gautami look good in tulsi role....who said she luks gud????she can't even cry properly.
2.when she enter in kyunki, most of them negative turn positive like(damani,taniya,bhoomi and other)....its because new Tulsi wud not have been able to tackle so many negative characters
3.love and respect for his family and no fight.....during Smriti's time there was more love n respect shown of Tulsi towards family.
4.mihir and tulsi love scene and mihir always with him in all problem...with Gautami's entry Mihir-Tulsi's jodi has lost its USP...there USP was to create romance without getting intimate..ppl say Gautami has gud chemistry but if she tries to create romance without getting intimate she will turn out be a major..that only Smriti cud do.
