i agree, but...
if y'all wanna watch Hamlet,
watch Hamlet. it should make a good movie but it doesnt. i saw this production without a clue as a kid, but have been haunted by it since. and that's the key - it's got to be felt more than seen because the way of a man lies in how he's haunted and that's what it's about. to this day, i would rather see the the Sheboygan Little Theatre version than the 5hr Branagh flick, because Burton set the tone for me back then of chasing one's pain by arguing with God and that plays onstage in a way that just cant on screen. especially at the top levels - the Brits anointed their young lions by giving them the Dane to quibble and, thereby, gave themselves the chance to watch their most talented, tortured & entitled represent them, enticing the gods down from the mount. i'm not even close to an authority but, far as i can tell, the Bard factored that into the piece
there are few better rabbitholes, but Shakepeare is like Italy - if you try to get it all in one trip, you wont. Olivier's a great place to start, because he lets one see how he thinks more than how he feels. but i'd take some time now, internalize what you've taken in, maybe read a little (Harold Bloom's
Shakespeare; Invention of the Human is great on many levels) and dive back in.
about the history plays (the Henry's et al), might i recommend Orson Welles'
Chimes at Midnight, in which he extracted the tale of Falstaff from those plays, which gives context to the tale.
my favorite Shakespeare movie - Ian McKellen's
Richard III
Good luck -
