I heard alot about this and it being the inspiration for the Showtime hit Homeland, that is screened on Channel 4 in the UK.
The series was run on a channel i can't get so got the DVD and just from the first episode, its excellent.
It has hard-coded on-screen English subtitles (Means they are on screen whether you want them or not) and as speaker of Hebrew, they are almost identical for translation, with just a few bits here and there changed to account for the 'lost in translation' reasons.
One downside i found though, is the commercial distributor of the DVD's, Arrow, were to lazy to translate the credits at the end.
They had the subtitles done, they translated the headlines of the papers and news bulletins, but not the credits. Very lazy and very poor for non-Hebrew speakers.
One thing i will suggest though is, expect alot of twists and turns, if you saw Homeland like i did first, don't watch this expecting a like-for-like copy because its not.
While some of the plot is the same, including the daughters' name, Dana, go into this like you haven't a remote clue what will happen, it makes it so much easier to follow.
Great gripping, shocking stunning viewing.
If you like that sort of stuff, i recommend hugely.
