In his book SAVE THE CAT, Blake Snyder recommended taking the “Pope in the Pool” approach to exposition scenes, meaning, if you have to have heavy exposition, make it interesting to watch, so the audience doesn’t know they’re getting bombarded with expo.

In the episode “You Win or You Die” of GAME OF THRONES, we get two “Pope in the Pool” scenes practically back-to-back.  The first has a man skinning an elk while delivering exposition, while the second has two prostitutes having sex as backstory is told to them.  I can’t tell you what the content was of either speech, but I didn’t get bored watching them either.
