This will be a really short review,
The story is a summary of our main supporting cast from season 1, on their meeting with bakarina and how they changed because of it. Its all from their own perspective, which we already saw in season 1, there were new scenes but it they aren't anything special.
If you like the series then its a good reminder on, how the characters connections were formed, but I would recommend not watching if you have just binged the entire series.
The production side was exactly like season 2
Overall it was fine and a solid 6, if you are a big fan you will enjoy it more.
