If you are seeking plot or theme, wrong film. It’s about the candles, plain and simple. If you look at this on YouTube, you’ll notice my son added a lot of tags, including a variety of spellings of Chanukah. Funny thing is, none of those are the way I would spell Hanukkah. My WordPress tag spells it like this: חנוכה (that says Hanuka in Hebrew). There’s only one way to spell it in Hebrew – or maybe one can spell without the vav in the middle, but the “real” way is with those five Hebrew letters.
Same son gave a d’var Torah (words of Torah) today in front of our shul. The gist of it was, one of the reasons if you are not Jewish that you may know about Chanukah is that we Jews have an obligation for what is called persumei nisa, publicity of the miracle. This obligation is unique to the holiday of Chanukah, and the reason can be found in history. The Assyrian Greeks wanted to the Hellenize the Jews, and they were a powerful force. The Jews had not had an adversary like this one before, one which worshiped the body and beauty. In reaction we are obligated to publicize that we are not accepting Hellenization by lighting the candles in front of a window and showing our Judaism.
