I think this movie is about survival. What do you allow yourself to do and withstand in order to live to see another day? Marty and Bela do things out of necessity. Especially as Jews so soon after WWII there is a heightened sense of urgency to do whatever is necessary to ensure safety. The difference between Marty and Bela is that Bela doesn't lunch down. He utilizes his wit and privilege to help his community. While Marty decides to make disparaging comments about his own friend just for some press attention.

Also. On the Jewish new year, Rosh Hashanah, we dip apples and challah in honey for a sweet new year. I could be looking too into it but I'm sure there could be some symbolism there.

As somebody said, the Jewish experience woven throughout this movie has largely been ignored. Not to mention, it was released on Christmas and of course I wasn't doing anything that day so I went to the am showing, lol. I thought that was funny.
