Hum sath aath hein is just another so called comedy serial, but to what extend its a comedy - it depends on the person who sees it.... as poined out earlier in this section of reviews, it definitely is a lot loud and strange, but perhaps it adds to the plot too.
As far as I understand, the only ideas behind the serial is to make each episode attractive with lot of colour and loud humour, pass on a small moral message (which at times are very good) and keep the light viewers (not catering to serious viewers) entertained for that time slot. And I think it does that job pretty well
Atleast its a bit of relief from the k - series which keep on showing tears, tears and just tears all through.... just recalling the proverb laughter is the best medicine, I think I would prefer such serials to those weeping womanhood of the k-series.
