On 21 September 2022, the Hoichoi authority announced that the second part of the web series will be released in December of the same year on the occasion of the sixth anniversary of the establishment of their platform.

[14] Miraz Hossain of The Business Standard wrote about the first part "Taqdeer famed director Syed Ahmed Shawki makes the series gripping with suspense intensifying in every episode, but the ending is so abrupt, unexpected, and intriguing that it feels incomplete, almost like not drinking water after a full meal.

[6][17] The art and entertainment desk of The Daily Star called it a unique storyline web series.

Poorna Banerjee of The Times of India rated Part one 4/5 and praised the performance of Chanchal Chowdhury, the lead actor of the web series.

[18] Saykot Kabir Shayok of The Business Standard said about the web series, "If keeping the audience hooked from the beginning to the end was the only criteria for a show to shine then Karagar season one passed with flying colours".

[20] Jannatul Naym Pieal of The Business Post said its editing was average and it disappointed at the end of the first part, but he praised its background music.

[22] Calling it an "ambitious production", Priyanka Chowdhury of The Daily Star does not think that this unfinished web series is unsatisfactory.

[23] Soumya Mukhopadhyay, the chief operating officer of Hoichoi, said Karagar has contributed a lot to its business growth in Bangladesh.

But according to him it represented the Bengali culture and turned into an excellent web series despite refraining from using sexuality and slang for popularity.

[26] According to Jannatul Naym Pieal of The Business Post, the story is fantastic but the director failed to convey it to the audience in the series properly in the second part.

[27] Poorna Banerjee of The Times of India praised the cinematography of Karagar but criticized it for having plot holes and lacking satisfactory answers to the mysteries.

[28] Agnivo Niyogi of The Telegraph thinks it was better to exclude unnecessary subplots from part 2 and the sequel is worthy to watch.
