Here's an assessment you've made of a 1980s film about which we do agree. Ghostbusters is a ton of fun, but it is a product of its time, and you'd never get away with jokes about ghostly blowjobs in a PG-rated film today. Still hugely entertaining, of course. My children love it. :)

My take (if you're interested - it mostly echoes what you say here). :)
