I agree with Sweet_JJ. Bella should really work on her interview skills. I don't know if the translations of her interviews were just not on point but in any event, she needs to learn a bit of "diplomacy."
I've only seen her in two lakorns, but I think, especially with regard to Khun Chai Puttipat, had it not been her, the show wouldn't have turned out the way it was. I think it was because of her work that James Ji was able to perform well enough on his first lakorn. The way she kind of interacted with James Ji's acting (I forget the exact term, but it's like the way they bounce off from each other) made it work, although her character in that Lakorn was far from perfect.
Of course I find her really pretty. Just hope they go easy on her eye make up. too much of it makes her look old.
