    enjoy wathced this, I like how they found each other (3 brothers), I don’t like BJH’s acting here…I’m sorry to say, but no expression n no chemestry at all, and It’s remind me JSY in Gaksikal who acted with joo woon, KJJ’s acting is awesome, BJH couldn’t balance him with hers, KJJ is too good for her (in this drama), 😉 bienne.. Just don’t like her acting not the person!! That’s my opinion., after all, this drama…its worth watching guys and happy end..I’m not KJJ fans, but after watched this, wanna see him in his next drama again… 😀

    Triangle just ended tonight where I live. I didn’t like the ending with Yang Ha dying. The writer could have handled the ending differently.

    I don’t think they brought Yang Ha’s role to his fullest. He was a lonely young man and he needed time to get acquainted with his brothers. Like the 2 brothers knew that Ko’s gang was out to get him, neither brother even bothered to call the police to help out. Thank goodness the other guys came to help out w/that lady’s help.

    I hope in his next film he will have a better role. I think he did well in this drama, he presented himself well in his role. I just feel they needed to have a different ending. Maybe added another episode with him getting hurt, but yet eventually surviving.

    I really enjoyed this drama. i didn’t like that the youngest brother died. Also, there should have been episodes between the younger brother dying, the father getting whats coming to him and everything else.

    I am SHOCKED that Kim Jaejoong did not receive an Actor’s Award from MBC! He more than deserved the Top Excellence Award, let alone the Excellence Award for his AMAZING acting performance in Triangle!!!

    Great drama…but is a great shame there is no chemistry between young Dal and his girlfriend…it made their love seem like child’s play…it was not right that the youngest of d brothers was killed off just like that…i cant ever rewatch this drama again…the director of Triangle should be careful when choosing Lead actresses…Young Dal was awsome! he over shadowed BJH his girl friend in the drama too much…
