Big budget historical costume dramas were still popular at the box office during the seventies although the public was slowly falling out of love with them. Cromwell is a curious addition to the genre in so far that it is actually demonstrably less than the sum of its parts. Despite a high budget and a quite impressive production design, it offers nothing more than a broad historical overview of the English Civil War and is actually quite light on detail and frequently historically inaccurate. It comes across as a somewhat long-winded history primer for schools and the viewer is never really offered anything more than a dozen or so bullet points of information about this period. However, it has a few merits to consider and is certainly not a total waste of time for those seeking a few hours diversion.
