Do the Simpsons have a film theme featured in each episode?

Question

If so, how are the themes presented in the simpsons? Are they subtle or are they pretty obvious?

Answer 1

no. sometimes there is cultural references but not in EVERY episode.  i think there's very little in season one, for example.  when there are, they are sometimes subtle, like the alfred hitchcock from "a streetcar named marge", and sometimes obvious.

Answer 2

I don't think so.
