Handsomedan:
Just started Gangs of London on Neon.
It's typical HBO-style in that it's obviously got a decent budget, it's well acted, scripted and shot.
It's not for the faint of heart, but it's pretty good if you like gritty, violent English drama that doesn't hold back.
Funny you should say that. I had started watching it a long time ago but for some reason had stopped after a couple of episodes. Wanted to pick it up again, so a couple of days ago I re-capped from the start. Currently up to E3. Really very good - but extremely violent as you say.
The reason I picked it up again is because I saw that second season was available.
