I watched the interview, and agree that Tucker did a terrible job, but not for the reason most people are saying.
I think it was good that he let Putin speak, because it gave a very good look into his mind and perspective (or at least what he wants the West to hear, which is in itself informative).
My problem was that the questions he did ask were stupid... Everything he asked seemed focused on US politics and on Tucker's anti-Biden/deep-state agenda.
