Homeyji,

Sitcoms or even serials in olden days were made with good script and better performance. Today most sitcoms that is being aired by major Nepali channels are slapsticks and cheap humor made with almost ZERO SENSIBILITY.

I remember, how whole 'chowk' used to gather up to watch Santosh Panta's 'Hijo Aaja Ka Kura' or even serials like 'Chakrabew', 'Tadha Ko Basti', 'Rupmati', 'Bhir Dekhi Bhir Saama', 'Gulaf Ekai Plata Fulcha', etc.  Serials made upon good literature were well made.

Today dominance of major international channels have just eroded Nepali Soaps, makers simply copy from Indian serials, adapt it into nepali society.
Sitcoms are the worst ones, TOO MUCH HAMMING, you wont be able tolerate their exaggerated expressions, their below the belt lines, LOUD ACTING makes you skip channel to watch MALLIKA SHERAWAT dances instead.  

So as far as I know barring few social dramas like  DEVI, MAHA's most serials, there are hardly any sitcoms that could be praised.
