I did expect a bit more from the DVDs. I hadn't seen the series but coming from who it does I expected it to be be high quality, which it was. Only that usually I could expect more, and this time was just good. Firstly no extras, in a DVD this sort, there could have been a tiny bit fo extras, there are always cut outs and things that had to be left out due time.. On the other hand it covers a bit of everything, and in quite an interesting manner. If I had to buy it again, I probably would, but only because of its contents, nothing spectacular about it. Maybe if it had been a tad bit longer and included some more information or experiments, even maybe reconstructions, would have been great.
If in doubt Recommend.
