What really annoyed me was the background story of Tin and his brother. I wasn't able to understand why his brother did what he did. And how it was gonna help Tin. It was very confusing.
It was a Tin and Can story so I understand why they didn't want to focus on Pete but I would have really enjoyed it if they did bring back Pete.
Although I liked Can's acting.
Other than that I don't think it deserves more than a 6. And if you are going to watch it then don't keep high expectations from the show.
