A passing thought about rampant remakes

As I told all my Facebook friends tonight: I can't help feeling weirded out by all these recent and upcoming remakes of '80s films that I reviewed back in the day. Because, really, I don't remember seeing that many remakes of '60s movies back in the '80s. Like, around 1987, no one was saying: "Hey, let's remake The Professionals with Charles Bronson in the Lee Marvin role and Burt Reynolds taking over for Burt Lancaster!" Or "Now here's a sure-fire hit: A new version of In the Heat of the Night with Eddie Murphy and Gene Hackman!" What's happened? Has Hollywood truly run out of original ideas? Or were the '80s actually a better era for cinema than I recall?
