I had only had a 65" TV in the past and going to 85" is a massive upgrade, this TV is so huge. I had no issues with the remote or apps but I'm using an Nvidia shield for them now so I guess that's partly because I like their interfaces better.
The main thing I wanted out of this TV was the super bright picture (my previous LG was terrible with it's handling of blacks and picture wasn't very bright)
I've been re-watching many movies and recently paired this monster TV with a Nakamichi dragon 11.4.6 surround system. Now I have to re-watch them all again lol
The attached video and pic shows both systems
Pros
1) HUGE!!!
2) super bright very realistic picture
3) Great blacks
4) I believe one of the best contrast ratios ever on any TV
5) Smart TV has lots of apps and a simple remote
Cons
1) stupid rechargeable battery that forces you to leave the remote upside down under a light source
2) You may find it hard to leave the house especially if you have surround sound as well
3) It's over 100 lbs so heavy and pretty hard to setup by yourself
