If your pre-flop reraising range is only QQ+ and AK, then I agree that it's a check because he isn't calling with anything that you beat. But if it's wider, like TT+, AQ+, and occasional SCs and PPs, then I think it warrents a value bet because when a smart opponent checks river after betting the turn, a lot of the time it means he's thinking, "I have a good hand, but if I bet I probably won't get called by any hand that I beat, and I don't want to get bluff-raised off my hand, so I will check-call a reasonable bet and maybe snap off a bluff from him."
