I hastily attempted to make this point in another thread, but did a very poor job of it and must apologize for that.
The point I was trying to make was: while B movies have always existed, up until quite recently there was no truly shitty movie that was both popular and/or a box office smash. Top Gun in 1986 might be the first, though someone can please correct me if I missed one earlier in the 80's. Thus my point about audiences once
being able to discern quality vs crap. Yes, even teenagers. Think about it, drivel featuring Pauly Shore or Seth Rogen would never even have been green-lit back in the day, let alone become box-office successes. Nowadays, the aforementioned Rogen drivel plus Transformers movies, Star Wars prequels, Star Trek sequels regularly earn boatloads of cash. Compare that to a list of movies with the most tickets sold before 1980, it's a list of nothing but classics.
Some of this might be obvious or rehashed, but at one point if there wasn't a good story there, the movie wouldn't be made or A-list actors wouldn't sign on for it. This point is highlighted by the fact that almost any AFI list or other qualified source of the 100 Greatest Movies or whatever will have virtually nothing from after 1970 except The Godfather 1 & 2 and maybe Jaws. In the current Top-10 Favorite movies thread on this board, I was genuinely happy to see that a few posters realize they used to make movies before the year 2000.
So if someone wants to insist that their opinion that whatever Pauly Shore movie they like is just as good as Citizen Kane or Casablanca, that is a delusional state of mind and should be dismissed out of hand, not supported by an "all opinions are equally valid" argument. LIKING something is an opinion, QUALITY is a fact. If that weren't true, then one should be able to state that Barbra Streisand is a terrible singer or Neal Peart is a terrible drummer and not be laughed at in the face. Sorry, the argument just doesn't hold water. There is crap and there is quality, it's not opinion-based. People
USED TO be able to recognize the difference.
Now I fully expect that almost no one will agree, and state that dogshit on a poster is as artistic as any Van Gogh masterpiece.
Well, carry on then.
