It's a nice combination of shootouts and a story starring two of the best Uncharted characters. The pacing is great, with the shorter length keeping it from outstaying its welcome, and the finale is probably my favorite of the Uncharted game endings.
I'm hoping that going forward, Chloe and Nadine continue to have starring roles (or at least lead a subseries) in the Uncharted games since they seem like more enjoyable protags than Sam or Nate.
