By the looks of it, the toughest job confronting tamil cinema directors right now is coming up with a full-length comedy which manages to atleast keep the viewer in his seat, even if not making him roll around in laughter, for the full length of the movie. We recently had Poovellaam Kaettuppaar which preluded a very funny second half with a listless romance. And now comes Minsaara Kannaa, which jogs along easily before becoming enmeshed in sentiments and cinematic cliches which make the last part of the movie all but unwatchable.
Indradevi(Kushboo), a garment manufacturer, is an avowed man-hater.
Completely surrounded by a lady staff, which includes her personal secretary
Priya(Rambha), she has single-handedly ruined competitor Vedachalam(Mansur Ali Khan).
Kaasi(Vijay) finds his way into her house as her driver and also into Priya's heart. 
But he keeps sparring with Indradevi's sister Ishwarya(Monica).
Vijay entry into the house is soon followed by other men including a gurkha and a
cook(Manivannan). It is soon revealed that Kaasi has his own secret agenda for entering
the house. The first half, though never quite reaching comic heights, is light-hearted
entertainment that produces quite a few chuckles. And surprisingly, Mansur Ali Khan and
his trio of inexpressive helpers provide many of the laughs. There are many amusing lines
scattered throughout and some clever sequences like Vijay getting the gurkha salute him.
There are two main twists in the movie and both of these manage to surprise. R.Sunderrajan
is the bungling police inspector, around purely for the comedy. But a later development
involving him and his junior Anumohan is a funny surprise.
The downturn starts once Vijay's secret is revealed. From then, onwards, the movie stumbles from one standard tamil cinema cliche to another. Kushboo's flashback, which describes why she hates all men, is too serious when compared to the rest of the movie. The same happened in Kaadhalar Dhinam too. Do our directors sign a clause that requires them to insert sentiments into every movie, irrespective of whether it fits into the movie or not?
