Roy Hodgson's side remain in second spot in their group after surrendering a half-time lead in the 1-1 draw with leaders Montenegro in Podgorica.
Hart said: "People ask about not holding on against Poland and Montenegro but they are tough places to come. Hopefully we will look back at last night as a good point earned.
"You've got to give respect to the opposition. I thought Montenegro were great in the second half and they made it hard for us.
"How I do assess the group? It is going to be tough. It is a really tough thing to qualify for a World Cup and you kind of take it a bit for granted."
