I agree when I was a kid all the older movies bored me. CGI might have helped.Old movies were the products of a factory system, with budgets and formula writing dominating the film making. Some became classics by pure accident. Great films weren't really done on purpose until the 'Studio system' died out, but the the costs soared as well and fewer and fewer films had more than one 'star quality' actor in them. These days, films are aimed mostly at kids, same as 'westerns' and action films in the earlier eras were. They're deliberately planned out to maximize all manner of 'profit centers' , like toys, clothes, etc, or 'action films', aimed at the rental markets. Most of the 'serious' films aimed at adults are mostly vanity films, stories a producer or director wanted to make and had the means to raise the money and attract the actors they need; few of them are 'successful' in Hollywood terms. Those get made because it's tough to keep screens going with just the big Star Wars type stuff, since those take a long time to put together and some filler is needed, plus the 'made for TV' satellite and cable companies need many many hours of filler as well, and some of those turn out to be enduring and good as well, again for the same the reasons the old 'Studio System' managed to turn out something excellent once in a while. Some directors are just better and more consistent than others, same with actors.
Remember bill Kennedy on sundays? God those movies sucked.
And back then you got one movie a week. Now we have turner classic movies all day.
