I hate it but that's because I was comfortable with WWE Network.
It's basically paying premium price now to watch them build the app again from the ground up. I'm sure it will look much better at this time next year and definitely 5 years from now but the lack of categories, no match/segment markers, a pointless search feature, the interruptions (even if you have the ad free version, it stops for a second or two where the ad marker is supposed to be then goes back to the program), and the having to wait for them to upload the whole library is annoying AF.
