I like it a lot. 2nd best UC game for my tastes, which isn't saying much, but still. It acts as a sort of "Best of Uncharted," riffing off of vibes from UC2 and UC4, with particular attention paid to how the game ramps up from the slow UC4 stuff to what I think is clearly the best end run in the series. It probably has the best puzzles they've done so far (and finally a tangible reward for doing them), the traversal from UC4 is made more interesting through better environments and climbing/jumping paths, visuals are incredible (of course), Chloe is a good protagonist (of course, best choice, Drake you messed up), the dialogue is fun, it actualizes the potential of the Madagascar chapter in UC4, and it gets better as it goes along. With that said it doesn't have the same emotional impact that an UC3 or UC4 might because it's basically a smaller scale spin-off pilot episode for a new series, but what it lacks in drama and scope it makes up for with a more constant juggling act of puzzles, combat, traversal, and quips. Considering how good the UC4 base is (controls, combat, sound, visuals, etc), I could see TLL with one more location and a few newer major sequences challenging for the best in the franchise.
There's no desert though so 0/10 on the LastNac scale.
