There's not a lot of love out there for _Shank_, but I for one quite enjoyed it. I understand it won't be for everyone, and I do come into it with a bit of a bias, but the only way you'll know for sure if you can appreciate _Shank_ (and decipher its various UK accents) is to watch it for yourself.
_Final rating:★★★ - I personally recommend you give it a go._
