Not what it could have been
The Birthday Party started life as a stage-play, which was largely slated on its 1958 debut, but has since been hailed as a classic. This version doesn't really show you why. Despite decent acting, it feels rather flat, perhaps since it is a very literal interpretation. The decision to leave out Lulu's flirtation with Stanley is particularly damaging. The later screen version (aired in 1987, as part of the 'Theatre Night' series) with Pinter himself playing Goldberg, Julie Walters as Lulu, and Joan Plowright as Meg, is far superior.
