I absolutely love this show, and so happy that the first season has finally been re-released on blu-ray!
The first season keeps it different, with a different monster each week. Only taking a couple of episodes this season to explain the mythology that has run throughout the whole series. It's great revisiting the early episodes.
The best part of having the first season being released on blu-ray, is finally having access to all the extras from the US release, as well as a few more great additional stuff. The biggest addition is the Road Map, something that appeared on the season 2 dvd.
The Road Map has interviews about the each episode's creation, running about 5-10mins each. Interviewing key members from the production. You can also toggle to read up on some of the folklore on each episode, as well as read 6 passages from the Dad's Journal.
Another big addition on Disc 3, is the Paley Festival Panel Discussion which runs at over an hour! This is a great Q&A, which is only hindered by a very boring and wooden interviewer. If you can get past him, you get really good information about the creation and running of the show.
Getting too used to other shows has made it annoying that there are too few episodes with audio commentaries. But the road map makes up for that a little, though not everything you want to see covered may not be explained.
Show: 10/10
Extras: 7/10

Audio: 10/10
This isn't a big thing, but the blu-ray was posted without a slip cover to match the other season releases (seasons 3-5 have a slip cover, I don't know about season 2).
