Memo to bombastic directors who come up with ill-digested “Philosophy for Dummies” concepts on the nature of love and life in hardly watchable films (e.g. Terrence Malick’s “Tree of Life”): Don’t. Unfortunately, chances are they won’t listen and will continue to come up with these half-baked offerings to convey a message so obscure we don’t get it. Case in point, “The Congress.” But before talking about that movie, note to self: Never assume that a director who gave us a masterpiece as first film will follow up with something half as good. High expectations set us up for big disappointments. So we’re mad when Florian Von Donnersmarck, author of the superlative “The Lives of Others,” hits us with a dud like "The Tourist"
