Let me put it this way. In the Malayalam happiness scale that goes from Chenkol to Ohm Shanti Oshana, I need something entirely on the Ohm Shanti Oshana side of things. Classmates, for instance, is far far too sad for me at the moment. Gandhinagar 2nd Street is too sad for me. I want the Malayalam movie where no one ever reveals their shattered past, and no character is left heartbroken at the end.
Now, the last time I made a request similar to this, one of my suggestions was Namukku Parkkan Munthiri Thoppukal, because it is a romance with a happy ending and also very good. And that is true, but along the way it is NOT HAPPY.
one fun movie I remember from childhood is Kathanayagan (available without subtitles)
recently I watched the malayalam original Nadodikattu and it made me slightly depressed as it deals with serious social topic of unemployment/underemployment
