Whenever I see someone recommend Much Ado About Nothing (1993), I feel like it should come with a warning. I see it come up in a lot of period drama comedy recommendations, and while the film is good and funny, if you don't understand iambic pentameter you're in for a very unfunny time.
Same goes for The Hollow Crown (Henry IV adaptation), excellent mini series, but again good luck following along if you don't understand iambic pentameter.
