Game of Thrones Series 1-3 were available for 60 days and have now been taken off the service (they were removed the same day as S4E1, which was available for 30 days). This is the downside of NowTV. Being a Sky service, it's getting the big shows (GoT, Boardwalk Empire, 24: LAD, True Detective, Penny Dreadful and so on) but only for a very limited time. Outside of that, there's a reasonable amount of content with long-term availability, but it falls well behind Netflix and Amazon in this area. Also streaming quality. NowTV isn't great. Probably the weakest of the three. And it breaks a lot, resulting in lots of free month/£10 shopping voucher promises that are yet to be fulfilled. I'd still take it over a Sky sub, but I'll probably take a break once GoT and 24 are finished (unless Penny Dreadful turns out to be really good or they get The Wire/Boardwalk Empire back on catch-up so I can finish watching them).
I didn't find much appeal in the Movies subscription. The back catalogue was no better than Netflix or Amazon and it was rare that I'd find a Premier worth watching that I hadn't already seen. This month the big films are Pacific Rim, The Internship, The Croods and White House Down. Next month it's Kick-Ass 2 and Elysium. Personally I'd rather rent a couple of new releases a month from Xbox Video or Blinkbox and get films that I haven't watched yet and I'm actually excited to see.
