For myself, I think I may have read Henry IV Part 2 once in college, but it never really stuck with me, it seems, because I went into this viewing completely unprepared. I definitely feel like I'll have to watch it again, not least because the King Henry-Hal scenes, and Hal on the throne (prematurely or otherwise) were heart-stoppers.

I also enjoyed the sauna scene, of course. Thank you forever, fanservice.
