Now more than any other time in history, Hollywood is cranking out sequels to decades-old films that had any sort of identifiable following, whether they were big hits or not, because Hollywood no longer has any idea what people like and assumes our tastes haven't changed at all since 1986.
6 Beverly Hills Cop 4
The last Beverly Hills Cop movie centered on a successful amusement park inexplicably printing counterfeit money and featured George Lucas in a speaking role as some random person who was clearly George Lucas. (This is another way of saying that no one has attempted a follow-up for 20 years.)

Initially, executives got the idea to do a Beverly Hills Cop TV series starring Brandon T. Jackson as Eddie Murphy's son, but wisely backed out when they realized that it has been hard enough to convince people to watch things that Eddie Murphy actually appears in, let alone a show starring someone tenuously introduced as his illegitimate offspring. So, the show was dropped and replaced with a full-fledged sequel starring Eddie Murphy and produced by Jerry Bruckheimer, making this the second or third mid-life crisis of Eddie Murphy's career.
