Tamil movie Dreams - Review

Goddamnit!
I wasted another 2.5 hours.
huh. I have no idea what message this movie is trying to say.
The director says drugs, smoking, etc etc are not bad in college, as you can come out of it and have a new life, but love is a killer virus and you cannot come out of it. Crap.
What kinda message is this?
Also the director , Kasthuri Raja, is the father of the movie's hero Dhanush.
