Admittedly series 1 was only a middling 6 Stars, at best, but if you can power through it to the Christmas Special you will find yourself watching amazing program the likes of which the likes of which you do not see every day.
Despite how this might sound to some, I would call this television show a British Little House on the Prairie with an updated world view. If buy episode 2 or 3 of series 2 you don't see the brilliance of this show ( for what it is ) that is all the more lost to you.
For very rarely is there such a clever, smart, witty, heartwarming, whimsical, serious and ridiculous television program. The characters will find their way into your heart and you will often find yourself smiling through just about every episode, if you're not alreally crying that is.
Though I might suggest new viewers start with series 2 and, after the program is over, go back to watch 1, I would strongly recommend this show.
