Being a teetotaler, I appreciate anything that shows excessive drinking for what it can really become. This aside, Weekend is a good movie overall, though for my taste Milland at some times says his lines slightly too fast and hammy (especially when in the bar explaining his drinking to the bartender). But all in all a well made film, obviously! I actually knew the film from Milland's appearance on the Jack Benny radio show after winning his Oscar, before seeing the actual movie itself. If you want a good laugh, look for it on any OTR website who offers free shows.
