Admittedly I only watched the first half of the game but I didn't find the home plate officiating bad at all. Kluber's stuff was just dominant, he was like Greg Maddux with an extra 5mph on the fastball. His arm slot is so consistent that you have no idea what the pitch is until you've wailed wildly at it. It was tailing back over the plate whereas Lester was a bit more off the plate and never would quite come back in the zone. I love watching pitching like that, it's a thing of beauty.
FWIW, I very much want the Cubbies to win but coming into the series I didn't give them much of a chance. When Cleveland picked Miller up from the Yankees, I figured Cleveland was the prohibitive favorite unless one of their starters did something stupid like playing with a drone.
