I watched this and I loved it! I really liked the fact that you couldn't predict where it was going. Sure, it wasn't going to end 'badly', like people dying, but the end game as definitely not given up. That's what kept me gripped. The humor is very well done, very subtle, as is the political aspects of this movie. I like that the director wanted to remind people of how life is in the occupied territories, but not in a lecturing manner. And we don't get beaten over the head with it either.
Some people have commented on the portrayal of Salam, and how the actor seems to just be wrong for the role. I beg to differ. I think he's perfect! The whole hilarious aspect of this is that he's kind of bumbling his way to the top. He's very imperfect, and bad things happen to him, but then turn into good things. It's just funny how everything just works out, so that's part of the charm of it. If he was a verbose, charismatic person, it would distract from the soap opera acting on the set within the film.
The best thing about this film is that everyone plays an important part in moving the story forward to the final outcome, even the shopkeeper with the expired canned hummus. No single actor or character steals scenes, everyone plays their parts and does a good job of it. The ending is definitely the best 'twist' ending I've seen in a long time!
Highly recommended if you want to watch a feel-good movie set in a difficult, politically charged environment.
