"The 1980s saw a boom in the popularity of massive film franchises and continuous sequels. After the blockbuster wave was initiated in the tail end of the 1970s with Jaws and Star Wars, studios were eager to be a part of the trend and churn out as many sequels as possible. In fact, many of the greatest movie sequels of all-time, such as The Empire Strikes Back, Indiana Jones and the Last Crusade, Aliens, Mad Max 2: The Road Warrior, and Evil Dead II were released in the 80s.
However, time has not been equally kind to all sequels of the decade, and many are still underrated to this day. Granted, nearly all of these sequels were financially successful at the time, but they still receive less acclaim from critics and fans, and tend to rank lower on lists rating their respective franchises."
