I have to admit, this is one of the most impressive and ambitious (in a good sense) bits of modern Tridentine liturgy I've seen pulled off in a while.
I mean, black vestments, suitably mournful skulls and bones, a synthetic tiara (!), ad orientem liturgy, incense, massed banks of candles, maniples, a subdeacon, and an enormous and slightly jury-rigged catafaque crammed into Rome's tiniest church? And asking for the repose of the soul of the great John Paul II? I ask you, what's there not to like?
