The Bees, who are currently second in the League One table, lost 3-0 at the New York Stadium last night.
"It wasn't good enough, that is it really," Judge told the club's official website. "They were better than us in every way. It is not usual for us to be outgunned and outplayed like that.
"They deserved the win, they were better than us. I don't think we can complain in any way, they were just better than us.
"I don't think they wanted it more than us but they got to the balls first, got to the second balls first and went from there."
Brentford return to action with a visit to face Oldham Athletic on Saturday.
