This was a nice drama to watch, a plot that merges comedy and more serious parts. I found a lot of food for thought but the funny scenes made the drama enjoyable and not too heavy or boring.
By the way, talking about the balance between funny and serious parts, PHS acting reminds me a lot of Jim Carrey and his versatile talent.
What bothered me were the too many drinking scenes (I don't think that drinking so much alchool is suggested when dealing with depression and taking drugs) and the fact that a lot of subjects where brought up without really focusing on one or the other remaining on a shallow level.
Lastly...the sub-plot of the friend betrayal was really unecessary.
