Its hard to be invested in the Beth and Jamie fued
Because there's no one to root for. Their both terrible unlikable people who deserve any karma headed their way. Beth is an angry vindictive bully and Jamie's a conniving weasel. I have some sympathy for Jamie because the way both Beth and his father bullied him really screwed him up but neither character has shown any signs of redemption. I'm still on season 4 though.
Other than John dying i have no idea what to expect in season 5 but at this point the best resolution would be for both Beth and Jamie to get whats coming to them and have Kayce step up and take over ranch.
