Do you universally like “new” movies? If not, what do you like about the movies you do like? I find that what I look for in a movie is pretty similar no matter what era it’s from:
Rich or just plain engaging characters, especially those in the middle-to-background - examples from a handful of eras for this: **The Big Lebowski **(1998), Cool Hand Luke (1967), **The Killing **(1956). I love all three for different reasons too, and picked them at random because I’ve re-watched them recently, but the commonality for me is that I could watch a whole movie or two telling the life story of any character in any of them. “The Jesus”, “Tramp”, and any Elisha Cook character in anything - in a good character movie dozens or hundreds of lives are introduced in perhaps minutes of screen time.
It’s not just characters, an engaging story, like Winter’s Bone (2010) or **Barry Lyndon **(1975 - Kubrick on the brain, and this is a poor example because it wins on characters, visuals and sparkling dialog too!) that’s told using the screen to do things that can’t be done on the page just gets to me. And I’ve read both those books as well - like BL better as a film and *Winter’s Bone *I think the novel edges out ahead but not by a ton.
I ramble on, but I guess what I’m saying is that for me, the age of a movie is only one element in how I judge or appreciate it. It certainly is important sometimes, but it’s rarely the number one way I categorize movies in my mind. So to me, your question doesn’t make much sense in terms of how I watch movies, it’s more like “why is any movie good?” And if you have an answer to that I bet I or others on this board can recommend a bunch from any era that might strike you.
As DrFidelius points out, pacing is one major difference between the bulk of “new” movies and the bulk of “old” movies. I’m no scholar of the concept, but I kind of think of it in pre and post-Spielberg terms. He and his peers kind of ushered in a style that sticks very close to Freytag’s pyramid while cramming in just a huge ton of “stuff” be it dialog, action sequences, effects or subplots, all the while relying on our culturally ingrained acceptance/expectation of the “pyramid” to help us keep the thread straight. For folks who are so used to this style of cinematic storytelling and no other, films that don’t use it can be damn boring. There are older movies that have a fast pace, though I’m blanking on examples, but most will have other barriers like archaic social attitudes or stilted, stagey acting.
In any case, if you don’t feel that your entertainment portfolio is lacking due to not watching/enjoying “old” movies, there’s not really a problem here. If you do feel you’re missing out (which I’d say you are but that’s just me) I think it would be best to narrow your search - don’t look for ‘classics’ or films that I or any other film lovers might thrust at you, look for something that specifically appeals to you on subject matter or other grounds.
And if it makes a difference, I’m in my late 20s and I don’t think of a movie as “old” unless it’s from before my mother’s time, say mid-1950s!
