I've recently watched DK and that's still fresh in my mind but still I watched the first epi of KTLK with an open mind.
First things first...the beginning was JARRING...HORRIBLE choice of bg music for the flashback of Ashutosh's past...sounded like a an animal dying or something whatever was supposed to be the voice of a kid singing...and I found the scene a bit rushed...as if they were just cutting from frame to frame to quickly show Ashutosh's past without letting the audience FEEL his emotions or the depth of his attachment to the house and his baba...dialogues weren't that great either. MB is a great actor but I don't feel the production values are doing him much justice.
Secondly...Nidhi and family...not bad...some scenes are straight lifts from DK like Nidhi walking along the wall to get to Anji's house...the bulb outside Anji's dad's office...the actors cast are pretty similar features wise to the DK cast...
I liked the scene where Nidhi is trying to touch her dad's feet but he wouldn't let her...the dadi bua is kinda OTT...but then the original in DK was loud too...the father is nicely cast and his scenes with Nidhi are good too but again, I get a sense overall of rushing with the epi...they don't really let you soak in the characters and keep jumping from one to the next in quick succession.
Another flashback I found rushed was Ashutosh and the lawyer telling him the house has been bequeathed to someone else...and it was unnecessarily dramatic too with showing him ripping the curtain
Anji-Nidhi are sweet together...
The cook is a very random character.
Overall I feel they tried to stuff too much into the first episode and they need to fix the pacing...this isn't a weekly like DK was and they need to fix the flow of the epis...seems like too much is happening in one epi only. The backgrounds of the characters need to be established better.
So overall, I didn't like the bg music much barring the few bits where they played the 'kuch toh hai zaroor' portions of the title song...and the direction is poor...nothing very impressive...production values could have been better.
