I really enjoyed using the site until around a year ago, when they suddenly removed all the friends/lists features. I liked clicking onto other peoples' profiles to see their reviews and ratings, and I even made my own lists of genre films so my friends could check out the shows I recommended. By taking that away, they destroyed the site's sense of community.
That's not the only thing that's happened in the last year: They removed individual season reviews from shows, made the UI on streaming harder to use, and of course raised their prices.
Personally, I made the same decision as Temis. I've watched some great shows and movies on streaming, but the majority of the shows I want to see are only available on DVD. I viewed streaming as a cool bonus, and it sucks that they took that away...I was thinking of alternating every few months just in case there's something special that comes up.
