He mostly uses the big conversation between the leads to give away an idea over the demon they think the marriage is. He serves it with humour and with ‘Bathroom'. Yes the so called room becomes the noticeable victim of the entire buzz of escape from marriages. It also looks like one of the blemishes in the flick.
The co-incidental meetings of Raghu and Gayatri, Raghu and Tara and the threesome together, falls in the category of flaws. Tara's casual behaviour after she gets dumped by Raghu also looks a bit unrealistic. But this doesn't perturb the entire screenplay which is picturised mostly in Jaipur.
