I've still got a couple of episodes to watch and the second series is just as good as the first, there is no drop off in quality at all. They missed a trick with this series though in how they've squeezed so much in in such a small space of time. They really could have shown the rise of Pablo over a season or two and then went on to when he hit the big time.
Also, the 'dramatization' is actually quite unnecessary. More than enough happened in real life for them to have to exaggerate and depict things that simply didn't happen. Something is taken away from the show for me, they really should have just stuck to the facts and it would have been just as interesting. On the whole though it's a very entertaining and well made show, if a little misleading in parts.
