Having been a fan of the two previous series of Skins and how the characters demonstrated, in some respects, a very realistic picture of the harshness of life I was sorely disappointed when this new series started.
As others have commented previous, the new characters are often irritating. I got the vibe that they had run out of ideas as the characters were so similar to their predecessors and the plots often weak.
From personal opinion, I'd give it a miss. It's not brilliant and lets down a fabulous programme!
