Their online selection was enormous ~2010 when they still had the DVD business, and crucially all of the movie studies still thought online was a fad and were happy to cut deals to stream their entire catalogs for pennies. Netflix was unbelievable back then and felt like it had every movie in existence. Over the years all of that back catalog has been clawed back and Netflix morphed into more of a showcase for their own content. But for a few golden years it was amazing to go in and like/dislike a bunch of stuff to see it just start recommending and streaming tons of classic films I always wanted to see.
As of last year when I finally quit, the DVD catalogue was still great, but service was so slow that it costs less to rent movies to stream individually.
