Yiannis, I am your opposite, I hardly ever see anything new since the early 90s. No wonder when taking my 8 yr old was £24 with a small drink and popcorn last week, that is robbery.
Re older film recommendations: If you say the Coen's are your bag, you probably have a handle on 90's indie cinema, but if not, google that ( I would single out the Jarmusch directed as favourites), then go back to 70's US indie cinema. There's a ton of great French films from the 50s to 90s. A simple thing that works is to check out the BFI catalogue of DVD's. If they issue it as a DVD or Blu Ray, it acts as a trademark of quality, for me at least.
