OK, this worked great as a one off ITV drama, with a good story, and some great acting, but it should have been left at that, a TV movie, not a pilot for a small series. The original first "episode" ends superbly for a movie, and should never have been followed on. David Jason gives a believable performance as both the simple minded prisoner with a hobby of collecting things, AND the genius Diamond thief. The story WAS good, strong and believable, but I felt that in the later episodes the thin story lines were predictable and I gave up watching after only two,and went back to watch the original. In a line, stay with the original,its much better.
