Don't listen to the nonsense people are posting here. Now TV is a very competent and well designed service which offers lots of benefits over traditional Sky TV (Q or Stream)

Firstly, you can use Now app everywhere, instead of being tethered to your puck or Q box.
Secondly, the discounts on offer are great - Entertainment for between 2 and 5 a month; cinema for 4 a month, Sports for 17.99 a month and Ultraboost for 4.
Thirdly, the HBO collection is fantastic.

Some negative or irritating things stopping this film getting a 5 star review.
The device support for 4K isn't the best. Also some of it makes zero sense - Chromecast Ultra supports 4k but the new Google Streamer 4k doesn't??
The fact Unboosted packages are only 720p.

Overall, very very happy with Now and it's a much better option than Sky for most people.
