I agree with some here.
TBH I still see netflix as great value for money. Its the cost in real terms of a couple of rentals from Blockbuster back in the day.
Which also meant you had a risk of not getting to see what you wanted and you had to return the bloody things.
Which then evolved into DVD by mail, where you got 3-4 times as much for the same price in effect, but still had to post them back, but you lost a bit in regards choice as you needed to maintain a list.
For the same you can watch virtually limitless content, you can do so on more than one device and also in other places, like on holiday.
I mean in that context, Netflix is the bargain of the millenium.
I always seem to find content to watch, but agree the rise of multiple streaming has seen dilution of some of the better stuff.
Because in this case its not competition, its fragmentation into a number of monopolies. If you want to watch show X you need to sub to a specific service. Thats not competition.
If they all, or mainly all had the same shows and were actually competing on say price, then what you say would work.
Each time netflix make a change people say, bah its going to hit their numbers, and yet the opposite happens.
I suspect for many people its hard to give up, I mean a decent size popcorn at the cinema costs practically the same as a months netflix.
