Since 1999, Law and Order: Special VIctims Unit has been one of the most popular crime procedurals on TV, and there have been plenty of changes across its 24 seasons. SVU is currently in season 25, but even its oldest episodes still make for great viewing. In the early days of the show, the focus was squarely on the exciting cases presented each week, as a team of detectives sought to unravel the tangled web of criminal deceit. In recent seasons, the personal lives of the detectives have become more important to the show, and it still produces some great seasons.
