This was a very well written series with an amazing cast.
The story went how I predicted with the exception of one surprise. Stranger doesn't have a bunch of twists and turns but that doesn't stop it from being thrilling to watch.
The creators did such a good job at making it so every episode was interesting. I never lost interest while watching even though I had an idea of what would happen. There is also some awesome character development and you really get to see it in the last episode.
The last episode was definitely my favorite and made me excited for Stranger 2. The ending was so well done! They made it so you can decide if you want to watch the second season or not. There is enough closure if you decide not to watch Stranger 2. I'll definitely be watching the second season though!
Also, poor Si Mok never gets to eat. Something always happens as he's about to eat in the cafeteria.
