“The Laundromat” (**1/2 out of four) was a well-made but not revelatory melodrama about a grieving widow (Meryl Streep) who begins to launch her own investigation into insurance fraud which leads her to Panama City in which she discovers that two law partners (Gary Oldman and Antonio Banderas) have been exploiting and profiteering from the world’s financial system. With that cast (including Robert Patrick and James Cromwell) and A-list pedigree including director Steven Soderbergh, it’s easy to watch………but it never connects emotionally and never shifts into high-gear and we’ve been down this road of big business, capitalism, and corruption too many times before. Director Soderbergh himself made a better film with similar themes in 2001’s “Traffic.”
