I recommended Peaky Blinders a few days ago. Another great box set is The Walking Dead. I wasn’t too keen on watching it as I don’t like zombies but it is so much more than that. You really connect with the lives of the characters in the walking dead and they are not afraid of killing major characters off.
The series is based on the magazine and follows the life’s of the people who have survived the zombie apocalypses. The main character is Rick Grimes who is a former police chief and it follows him and other survivors search for somewhere secure to live.
There are 8 seasons and I found these gripping and at times it made me shout outload with the shock. You can catch the first 7 seasons on amazon prime and the last season on sky store.
