I wish I could recommend an opinion today that was profoundly worth general reading, but no such luck (at least yet).
In the meantime, if you want to read something extremely erudite -- yet exhaustively boring -- here's an intricate civil procedure opinion by Justice Evans that should have you riveted. So long as you are hugely fascinated by the intersection of federalism and the Supreme Court's collateral estoppel jurisprudence as applied to the ostensibly procedural federal two-dismissal rule.
Engrossing indeed.
