Well so far PR has been going pretty well. Nothing has been glaringly and utterly ridiculous.
Mitts is correct though, although I never watched Kyunki... and Kasauti..., I did watch Kkusum, and that started off well but was just crazy after the initial parts. I really hope that PR does not go the trademark BT way, with the ridiculous and rehashed storylines, which include tons of new characters and families who are all scheming and out to get the main leads, deaths & rebirths, becoming instantly rich/poor, multiple marriages/affairs, years of separation, illegitimate and unknown children (who also fall in the scheming new characters section), and many more such show-ruiners.
The treatment of PR's story has been very original so far (atleast in comparison to other serials in Hindi), and I hope they continue to be original in their writing and keep the show legitimately interesting with an ACTUAL PLOT. Keep it up Mr. Joshi (and please give due justice to all the villains as well as Archana and Manav.)
