I set a recording (DVR; cable TV) for it and watch the first hour the night it airs. Then, as I'm waking up in the morning, I zip (as in fast forward) through the rest until something that looks interesting (not often) comes up. Yeah, the last 2 hours go very quickly.
For the PPV shows, I stream via the WWE Network and watch on my Apple TV 4.
I watch Raw on hulu so I don't have to go through 3 hours of it. I paid for the network for 2 months and watched the PPVs through there when I had it, but once the nostalgia wore off from the old matches I cancelled. The other content didn't interest me and their PPVs aren't exciting enough to make me want to use the network ever again. So I just stream them now.
