Completely unrealistic, in starting you will feel good based on reviews, as the path progresses you will realise thay are just trying to connect with previous dots but actually direction fails completely to do so.
If you like unrealistic and fake series you can go for it.
In the end you will feel cheated and time wasted.
Save time in watching a good series which makes you feel good and talk about.
If you like real and practical series just comment will suggest some good ones I saw.
