I hear you! A lot of movies these days are either obvious remakes or the sneakier kind that don't actually give credit to the original they've stolen from. I watch a lot of films with my wife that I can identify as stolen from an older film but they're often ones she never heard of or watched. And new films for a variety of reasons don't often please me, though the details of that statement are too long to discuss here.
When I read what you said about older movies (and you're spot on about poor dialogue being rampant) I first thought of some Vincent Price films as good classics. Have you ever seen Diary of a Madman? It's an excellent horror movie based on the short story "The Horla" by Guy de Maupassant.
For newer movies (and by newer I only mean not silver screen, because my concept and tracking of time is very bad
) let me recommend Once Were Warriors to you. It's a foreign film, offbeat for an American audience but very powerful.
I'm not certain how much our taste in movies align, TrailMyx, so I'll leave my recommendations at that for now.
Hopefully we can revive that lost love of films, haha
