This particular production WILL become the definitive Hamlet for a generation. People will say this is purely for Tennant and Stewart. For the most part they will be right, but perhaps for the wrong reasons. Undoubtedly the pair have avid followers from their many years in science fiction, and here they feed off their previous roles. Rather than detract from their performances, I say that experience enriches it. Here both play similar characters to what they've become famous for (though clearly with a twist - especially in the case of Stewart, who plays the villain with elegance) they appear completely at ease as Hamlet and Claudius, when it seems other members of the cast are not so comfortable. Until Ophelia went mad I kept wondering 'what on earth does THIS Hamlet see in her?', and Laertes had no strength of character, no real sense of threat - even when he pulled a gun on Claudius. As for Rosencrantz and Guildenstern...anyone who has scene Tim Roth and Gary Oldman in the roles will probably consider this pair a minor let down.
However, Hamlet, Gertrude, and Claudius demanded my full attention every second they remained on screen. The time spent watching them was a pleasure that moved me both to fright and laughter - some times in the same scene. By the last I was reduced to tears, as it fitting for the finale of a tragedy (though I admit I'm not usually one to reach for the tissue box).
There has never been another RSC production where I've felt so jealous of all those who saw it on stage. You lucky, lucky swine.
