This week, I finally made the jump to cancel Netflix before my account renewed on the 12th. — So, now I have 7-days to mail back my two remaining movies, and then receive no more.
… Why did I cancel? The reason is: movie fatigue.
I'm generally pretty busy, and once you're past the initial “honeymoon-phase” of first having the service, you start to get used to the same amount of movies always being available and therefore less excited about finishing them and starting new ones. There'll always be more and newer movies coming out, and there are already so many.
This also coincides with movies that I'm less excited about watching starting to move lower and lower in my shipping queue. — After I watch the movies that I really want to see, I just wait longer (weeks at a time, sometimes indefinitely…) to watch the others.
Overall, the service is still great, but it's just not a good value unless you're constantly refreshing and cleaning your queue of discs you don't actually want to watch. — There can be shipping delays, though, and the streaming service doesn't yet have most of the material that I want to watch, so that sucks. It's kind of a lose-lose for me at this point, especially for a fixed monthly-fee regardless of actual screen-time and discs completed.
