I rent movies about once a month so I use Redbox to view the latest and greatest. They don't have a great selection, but they usually have something that I want to see. They do put in older movies in their rotation.
At $1, you can't go wrong. They do have very good customer service online for the occasional damaged DVD. They also offer free codes that I've used numerous times.
I'm careful as to when I rent so that I have time to watch it twice before returning it. If something comes up, then I only get to see it once, no big deal. If I only had time to watch once, then I get a call from work, it's a waste of a dollar.
I've never used netflix. Somehow, I just don't trust paying for 1's and 0's without physically holding onto something especially when the internet connection is fallible and slow (for streaming video) at most times.
