I want to see how much value I can get for my $7.99 a month. For example if I watch 200 films that works out to about four cents per film.Malkoff makes an excellent point: Is the all-you-can-eat streaming from Netflix a much better deal than their 1-DVD at a time which is the same price?
If you were able to watch every movie that came in the mail the day that you got it, the maximum number of movies would still be approximately 10 per month, or 90 cents per movie. A more realistic estimate might be 1.5 movies per week, which translates to about $1.33 cents per week.
And what if you wait all week to watch a movie, and then the disc is scratched?
While people often complain about the selection on Netflix Instant Watch, it certainly makes more sense to watch a TV series like Walking Dead or Battlestar Galactica from the beginning using Instant Watch rather than watching one DVD, mailing it back, then watching the second or even third disc in the series.
So, if you end up watching a TV series or two, plus 5-6 other movies over the course of a month, Instant Watch could be a better deal for you. But if your priority is to see Mission Impossible: Ghost Protocol etc as soon as it's on Netflix, then stick with the by-mail option
