As Replican Era dramas go, I actually was compelled to keep watching it to see what happens. Most of the time the intrigue is rather stretched out or lame, but the tension in this drama as to who is suspecting who and who is really 'the good guys' I thought was pretty good. There are some weaknesses in the plot and an ending you may not find satisfying but it does reflect the title--'best' assumes best friend but....?
As for the visuals, the costumes on Sebrina Chen were marvellous, the baby is a cutie, and ML made me think he could be Hawick Lau's brother.
