For some time I like to find various top charts of movies, music, books and others and just consume the top stuff.
The best way is to start with best rated (e.g. IMDB). Next is follow curated lists (best books from New York Review of Books) or competitions (Grammy, Oscars, Pulitzer prize).
Also top sellers lists are usually good source (e.g. best selling albums per decade).
If something appears on multiple list (best seller, top rated, picked in curated list) usually it will be amazing.
Focus on the great stuff, not on current trends.
