Was I too passive in this WA/WB situation? Can I call this river?

I don't mind a flop check. This is a 5way limped pot. Not all that much good is going to come out of betting it. It's not horrible, but I personally prefer a check because I'd like to see a reasonably small final pot size.

Checking and seeing what develops is fine, I think. Our hand actually improves (debatable) a little on the turn. We can donk a modest amount and comfortably fold to any raise. It's better than c/c anyway. Cheaper, and there a few better hands and lots of ties that actually fold. Re-examine river if called.
