Uppum Mulakum

As the title suggests this sitcom declined because at first most episodes were hilarious due to the performances of the leads Balu, Neelu, Mudiyan, Sreekuttan and Lechu and not to mention the kids(shiva and keshu) had lesser roles back then, later the kids became the back bone of the comedic situations and they just weren't funny enough, they just came off as cringey. This happened around episode 600 but even in the 600's some episodes were funny, it was was the 700's where the word funny could not be used to describe the show .Honestly reminds me of the Simpsons, iconic at first and then became bland.
