Life Is But a Dream covers a…period of time before the supposed birth of Beyoncé and Jay-Z’s daughter, Blue Ivy. It’s hard to say exactly how long because particulars like where and when are barely telegraphed – there’s not a single explanatory chyron in the entire film. Cynically, I wonder if this is a sign of co-director Beyoncé's egocentrism; she assumes that we’ve been following her closely enough to know what she’s talking about without bothering to explain certain key facts. Or maybe she thinks we can read her mind. Or maybe she’s just not that great of a memoirist.
