Basically every line that Hamlet speaks is a pun or joke of some kind. Hamlet is always stuck inside his own head, which is why he can't 'act' for such an long time. Alex Lawther played the whole thing so sniffly and angry -- he was ready to shoot Claudius in the head basically right as act II started. Where is the playfulness or depth? To me it just seemed shallow and loud for such a lengthy performance.
