We can all agree on Bombs acting... I hope he improves AS the story goes along. He certainly looks the part; he's Tall, dark, and handsome. I think the problem is that he doesn't have control over his body. His limbs are so long on him that he looks goofy sometimes. If he can practice his stature and pose a bit more I think he would feel more comfortable as a Mob boss. It's like he doesn't know how to stand and showcase confidence. His shoulders are always drooping. This was also mentioned when him and the other "Khun Chai's" were training for their roles. Bomb's problem was his stance. He has a slight lisp when he talks too fast which can make his words sound slurred and weaken his Mafia appearance.
I am impress with Mint however (as everyone is). She really improved a lot. I didn't think her acting was bad before or anything, but in Cubic specifically she plays a main role. She isn't overshadowed by anyone else. We can see more of her skills and I think she will shine even more after this lakorn. I don't think that she's anything near "ugly". I wished they tried to make her "uglier". Maybe some wild curly hair, some dirty nails, chappy lips, dark under eye circles or something because eliminating her makeup doesn't exactly mean she's ugly. If anything she's prettier looking "natural".
Noey is one of my favorite N'rais. I can't hate her no matter how gross or horrible her characters are. She's sexy, and definitely full of talent. I was instantly a fan of hers when she played in "Ai Khun Pee" with Pat Napapa and I forgot the actor's name.
Pra'Eks who played the mafia roles pretty well: Chakrit, Om Akkapan, Smart... that's all I can think of for now.
