Sam and Rohit have great chemistry according to me. Their chemistry is the reason why i started watching this show (chemistry is a subjective thing some might feel they don't and that's absolutely fine)
Sam is a good actress. Only a very few actresses can do those bubbly and fun characters and not look cringe (to me atleast) and Sam does that effortlessly. She's great in scenes where she is bubbly. Like Abhira was in early days of this gen. Her emotional scenes are a hit and miss for me. Some scenes hit very hard but some are not that good. Also she's good in scenes when she acts fierce, where she acts badtameez. I personally love it and enjoy it alot.
Rohit is great in angsty and subtle emotional scenes and intense romantic scenes. I don't like his phoot phoot ke rona (woh toh kisi actor pe suit nahi karta) . My favourite performance of him is ofcourse the drunk confrontation with dadisa after sangeet and rumaal revelation.
Anita Raj is again one of the best actors of this gen.
Garvita was awful initially but still better than Prats. She has improved alot. She was really good in the scene after Ruhi found out her baby is no more. Also she was really good in her breakdown after Ruhaan wedding. She can not do bubbly and chirpy Ruhi well. She was unbearable in the phase when she was good to Abhira and her early pregnancy phase. Those mood swings and all. Awful.
Apart from these actors i feel like Sachin (Manish Goenka) that stands out the most among the supporting cast. Also i really like Phupasa and Manisha.
Saloni was really good in Charu's wedding track. She definitely deserves a more prominent role i hope she get more ss in the upcoming episodes.
Shruti (Vidya) is just terrible. She's too ott for my liking.
