First couple seasons defiantly worth the watch. However I'm going to write my review on the newest season as that's why a lot of people will be here. In short it's a tough watch. Not because the programme deals with tough issues or themes, but because it's so dreadful. Poor effort coupled with the most ridiculous scenes that appear frequently. Clays paranoia is so overstated and fictional, it's just laughable. I think it's designed to sort of hint at that toll the stress has taken on clay, but it comes across as just poorly done and pathetic. Their are genuinely good moments but they are tarnished with such misfitting odd moments that take a lot away from the overall show. Finally the amount of awful I mean awful decisions made by clay and others are so annoying. One after the other, it seems the plot relys heavily on this continual spiral of blatantly bad decisions. Moreover a group of boys somehow take a vested interest into a resolved matter, and seek to go well out of their way too seek revenge from a situation which is removed from them. Pretty horrendous shame this series had a genuine spark to begin with.
