“Disclosure” can be an awfully loaded word, one that carries connotations on multiple levels, both big and small, but nearly always with personally meaningful ramifications. However, sometimes those implications may be so subtle that they’re not easy to spot, grasp or understand, even though that does not diminish their importance. It’s also interesting to note how they’re frequently revealed simultaneously, heightening their impact, especially if they’re considered in tandem with one another, a circumstance that may be hard to ignore. Such are the dynamics at work in the latest offering from iconic filmmaker Steven Spielberg, “Disclosure Day,” handily the director’s best picture in years.
