Difficult time finding movies, International, foreign, black and whites, old movies, etc.

I find it very hard to find movies now.
I would like to know the top 250 movies of black and white.
Or between 1960- 1970 for example.
I would also like to just look at movies that are international.
Foreign movies and their ratings.
I feel everything was thrown into a box and now is all mixed up.
It hard to find Titles and things of interest now.
I hope that searching would become more easier.
The site has become difficult to use for research or looking up things.
