In my opinion, she may be the only lady-comedian now but she can't be compared with Manorama and kovai sarala.. Too monotonous..
I agree that she is good, but also monotonous. The problem is lack of good writers. After few films we even feel Vadivelu, Vivek's comedies and their dialogues were over used. Coming up with more humorous, witty lines and clever plots I think she is capable of doing very good like Kovai Sarala and Manorama.
