I'm not G4 fan but I used to watch their MSP series and quite enjoyed it. When the official trailer of MLMU was released, I felt a bit odd as it seems like the acting is not as good as I expected. This feeling maintain the same when I watched 1st ep. 

Fourth acting is ok but in some scences it seems like he gets exhauted and turns out to be stiff. 

About Gemini, his acting is a bit no for me :( Tbh, he doesn't do well in those soliloquy scences. I was extremmly impressed by the actor played Ida role in Japanese ver. He did really well in those soliloquy scences so when it comes to Gemini, I was really disappointed. His acting in those scences is so boring and stiff. It makes me feel a bit annoying and really dont want to keep watching this series. 

Both fourth and gemini acting make me so confused. I wonder have they ever pay attention to train their skill, like taking some acting skill class to improve or so. 

It's kinda disappointed somehow as I like the original Japanese manga. I used to watch the japanese live action ver then dropped after few episodes as I couldn't stand the "overreact" Japanese acting method. That's why I was very excited knowing about the thai ver. But when it's released, it's just so... plain. I'm kinda dragging my feet whether i should keep watching or just drop. Hmmmmm. I wonder will it gonna be better for the next episodes or just keep plain like this.
