I think probably you need the context: Adam Curtis usually makes multi-part documentaries that span several hours, so his blogs have a pretty serious load on the old attention-span. That said, I've never yet been disappointed by the way he puts them together. He's very much a storyteller, but at the same time as he admits to weaving in his own opinions, he does at least do his dues as regards research. Some of the archive material he unearths is unbelievable, I swear he must just live on a camp bed in the BBC archive.
