The primary actors carried this episode through the hour of what can only best be described as torture. With no major plotline or points of serious interest, the only mystery (and minor at that) of this episode was solved within the first 10 minutes, leaving another 40 for us to be bored senseless with aimless drivel. The topic, despite being one that desperately needs an effective and hard-hitting dramatisation, was not done justice due to an overall aimless script in which I failed to find much good drama or effective storytelling.
The guest actors for this episode, despite some of them being successful and effective actors in their own right, were severely let down by the lack of good writing structure, poor choice of dialogue and complete ignorance of real social situations. To read that Timothy Prager, the apparent author of this episode, is a semi-successful screenwriter was surprising to say the least as what was put on screen felt more like the writing of a struggling high school drama student.
The mere 2 star rating for this episode was kind at best and only given due to its tackling of the content and the intention it had in exposing the truth behind drug addiction in the UK.
I would suggest skipping this story which (regretfully) carries on for another episode - it doesn't add much to the overall storyline other than incorporating things we've already seen in previous episodes. Do yourself a favour.
