Now days you can get internet for $50 or $100 (depending on location, speed etc).
Then if you wanted say 5 of the various platforms, that's going to roughly be $50 to $70 more. So that's still a likely savings.
And on top of that, all new movies are basically being PRODUCED by these networks, so for the most part you don't need a theater (or their prices).
And on top of all that, instead of just fully subscribing to all of them, just get one at a time. Want the new Dexter series, get Showtime. Done with that? drop it until season 2 is out.
So it definitely can be a lot cheaper than the old days.
And yes, it definitely can be cheaper if you willing to actively manage what subscriptions you need and don't need one month at a time.
Its significantly better than cable TV still. I also dont get people reminiscing about one streaming service dominating, we shouldnt be wishing for monopolies. Everyone coming out with their own platform should drive up competition and give us better quality services
