Find an individual reviewer you agree with and follow them.
Exactly! You can also find more than one to follow, and take note of which never match your tastes. For me, I will avoid any movie recommended by PBS’s Patrick Stoner until/unless someone I trust tells me otherwise. I used to have two critics I particularly followed. One had the same taste in foreign film as I, and the other was ready to enjoy a stupid Hollywood rollick. Alas, I’ve lost track of the former and the latter is now at Slate doing a variety of stuff. The result is I pretty much stopped going to the theater.
