Interesting set of characters. I love that there is at least 1 person much older than the rest. Mostly in Hebrew subtitles, (I'm an English based viewer). Some things said in English, occasional dialog).
Great juxtaposition of people doing well and occasionally flubbing instructions. Lots of nuances into the main character's backgrounds--which keeps you watching. One criticism, the American brothers seemed too juvenile--almost cartoonish. Why would the government even bother with people like these.
I'm not well versed in the spy business, but I did expect Mossad to be harder on the trainees. Maybe that's the mystique. Still very riveting and interesting. Looking forward to more episodes.
