No one's the best just yet, everyone has room for improvement...but to say Pinky isn't doing well in WWHJ doesn't seem right, when a lot of people watching the lakorn right now are convinced of the opposite.
Just because a lot of people are watching WWHJ, it doesn't have to do anything with talent. Well I take that back, it does have to do with talent but looks, plots, scripts and popularity are also factors. And sometimes one overpowers another. I have been following Pinky's lakorn since she was young (Dao Prasook, Bla Boo Tong, Mane Nopa Gaow, etc) and I think she acts better when she was a child. She has improved in certain area, but when she cries, it is the same way I feel about Pancake's crying.
Pancake on the other hand, convince me when she is angry, she actually somewhat has emotion. As for Pinky, it's like she just yelling. Pinky is not a bad actress, but I just feel that she hasn't improved much considering she started out as a child star. Pancake, I like her acting but when it comes to crying and acting all cutesy, it is a turn off.
As for Mart, he can't act. But when he is given the right roles, he's great (MKKW and Dong Poo Dee). He isn't great playing sadistic roles like Likit Kammathep.
I love Rita, but I admit her acting isn't all that great. Some people are gifted with great voices-she wasn't. But I admit she does have some sort of emotion when it comes to crying. But when she gets mad, it is definitely not convincing one bit.
I could go on forever but as of right now, I can't name them all. Actually every actors and actresses, regardless of how wonderful their acting is already as is, there is still room for improvement. Some needs more than another.
