The show is great and well worth the watch.
I had held off buying the DVDs as they were individually released hoping for a full series collection that would combine the four DVDs into one packaging for more compact storage. That didn't seem to happen. Instead it is just the same DVDs you can buy individually, in their own cases simply stacked two by two a thin cardboard box. Which could be annoying depending on how you store your DVDs. I'll probably not even keep the box in the end, which is a shame because it looks cool.
Ultimately it's a slightly cheaper way to buy all four of the DVDs if you haven't got them already but there is nothing to make you switch to this collection if you already had one or two of the DVDs.
