The South Yorkshire Star has
a clip of Hamlet from the scene where he's plotting to stab Claudius during his prayers. The audio quality isn't great, but it's a nice clip.
Frankly, I don't see what the reviewers are complaining about. His diction is very clear and pure and doesn't come across as too posh or artificial at all. C'mon, Hamlet is a bloody prince and this is Elizabethan English!
