Ehh.. That's a big bet.

It's way too much to price out any potential draws he could have and blows him off a lot of mediocre hands that would call a smaller bet.

Generally it's unnecessary to make pot sized bets on the turn or river. In fact, it's usually not necessary to do it on the flop either, but it's not as bad since the pot is smaller absolutely.
