There was one thing that annoyed me about this series once it started, I did not believe the core group of friends actually liked each other, if anything it felt like they only hang out together out of convenience but wouldn't miss an opportunity to belittle or mistreat each other.
But I think it was concise, since the story starts when the group starts to fall apart, when they reach the limit of what they can take from each other. It almost feels like a coming of age story where the main lesson is self love and worth.
The acting was top notch, while I think that Force and Book struggled with their characters and had a more lackluster performance compared to the others, at the start everyone still needed to break in their roles, Neo was the one that I felt was the most comfortable and ready for the challenge from the get go, Boston was probably the most different character he has played and it fit him like a glove, I was in awe by him. Khao had the hardest scenes to film and just like he did in Moonlight Chicken, he showed once again that he is one of the greatest actors in GMM, his character can give you a lot of mixed feelings from hate to pity, but it's certain that he will make you cry. While I think First bit a little more than he could chew with Sand, he still gives a strong perfomance, the chemistry he and Khao have is undeniable and allows the relationship between the characters to be believable and captivating even when it shouldn't. Mark was a pleasant surprise, Nick is a character to feel sorry for, with a lot of vunerability, I think Mark's performance was well done.
I feel that Cheum as the only girl of the group and the lesbian representation you rarely see, could have had more space in the drama, I would like to know more about her relationship with her girlfriend, while they treated her as the glue that keeps the group together, she seemed so out of the loop most of the time, her character was the hardest to relate to.
The story wasn't the best, but the execution justify why Only Friends got so much attention and praise, it is about people, about relationships, friendships, drugs, sex and betrayals.
I can't even say if it has a happy ending or not, because the end doesn't feel as a end, because life doesn't end after the credits roll, it keeps going, so I can only imagine that it will be the same for these characters, they will keep going and we will see Nicks and Sands and Rays and Mews walking around making mistakes and trying to get things right just like everybody else.
