If you had asked me a year ago about Amazon Prime Movies, I would have said they are crap (just like Netflix) and the player doesn't work on anything but Apple or Fire, but that isn't true today. The player works fine on all my Android devices.
I looked at the movie selection last weekend and just in the first hundred, I spotted:
MI: Rogue Nation
Terminator: Genisys
American Ultra
Interstellar
Mr. Holmes
Hot Pursuit
A Walk in the Woods
Transporter Refueled
All those are newer movies that are out on DVD but most haven't aired on premium cable channels yet.
Furthermore, in that list of 100 I spotted:
Oceans Eleven
Twister
Matrix (all 3)
Rainmaker
Casino
Ex Machina
Gremlins
Big Lebowski
Hunt for Red October
...all watchable movies, and you seldom see decent stuff like that on Netflix. Netflix blows for movies unless you are after the 10 year old straight to DVD stuff. Netflix is great for Series TV, but Amazon is no slouch there either. And since they are about the same price, the other stuff (music, books, and shipping) place Amazon way ahead in my book.
Movies and stuff aside, the shipping alone is worth it to me. Sure, I can usually find what I am buying for the same price with free shipping (non-Prime) but it won't be here in 2 days. And even when shipping time is not important (it almost always is), I seldom find items cheaper elsewhere, and shipping is still free on pretty much everything, just slower. It isn't often I am OK with waiting 7-10 days for something I bought.
I recently got a month extension on Prime over a $5 set of glasses cleaning cloths that got lost in USPS. AND I got the $5 refunded so if they ever show up I get them free. And a few weeks ago I got a 25u rack (about 85lbs) that was missing some pieces, so they shipped a second one free, I took what I needed and UPS picked up the remainder, all for free. Last I checked, 2 day air on 85lbs is about $150. That one purchase saved me the entire year of Prime and then some, and if I had bought that on Ebay and came up short, I would have been paying several hundred in shipping to get it worked out. Took 2 days to get parts and cost me zero.
Last Christmas I found something at Costco for less and got it price matched on Amazon. I don't look often though, and only call if there is a problem.
