If you've not seen the original Israeli series you should give it a try, much better in my opinion (although I did enjoy Homeland).
There's always something a tad tacky about Homeland compared to, say, HBO's best shows, but Danes and Patinkin really are spectatcularly good. The guy who plays Brody not quite so much.
I think Brody is going full Jack Bauer next series. The whole going dark ending reminded me that this is from the writers of 24.
Would give both seasons 8/10.
