The reviews for Fanaa are full of praise of Zain and Reem saying that Reem is highly talented and it's a treat to watch Reem as Pakhi. But I don't know when I see Pakhi O don't get connected to her as a real character. Like I know the entire time it's Reem and she's clearly acting. Even Zain, when I compare her to Jennifer Winget or Karanveer Bohra in Saubhagyavati Bhava. I don't get that unsettling feeling from him neither do I sympathize with him.
As for Reem, it seems like writers think her only role in the show is to look pretty. She's at best average in the show and there's nothing to suggest it would make any difference if she's replaced by another actress as Pakhi. Tbh, I don't get the acclaim she's getting for Paakhi.
Now coming to the only one who makes this show bearable, Ayaz Ahmed...As an actor, I feel it's Ayaz who's doing the best job amongst the cast. Like the guy is insanely good. Despite being a minor supporting character, he stole the show with style. I hope he gets a main lead role after this that justifies his acting chops.
