Eh, aside from pacing issues (more towards the end of the first act and the beginning of the final one, I typically don't mind slow burn beginnings, myself) it's a pretty tight gameplay experience. It has some of the more annoying trappings of narrative driven wide-linear models of AAA games in the past few years. it flirts with market tested 'widest net possible to catch the most diverse fish,' gameplay mechanics without actually committing to any that change the formula in any substantial way. There's elements at play that just reek of "we put this in here specifically because it would make a nice quotable paragraph in reviews," like the Madagascar section.
The few new mechanics that do get introduced are used over and over and not changed up to increase the difficulty, or make the player think about things too much. TLOU2, for all it's vitriol, be it earned or not, does a little better in this regard with a few variations on rope puzzles and what not. Uncharted 4 is essentially just "look, a rockslide! Look, a grapple point! Now check this out, a rockslide AND a grapple point!"
Also, there's this weird quirk where Uncharted influenced the Tomb Raider reboot but the Tomb Raider reboot clearly influenced Uncharted in turn, and it creates a paradox that just screams dev laziness in the name of throwing all of their money into visuals.
That said, what worked before works the same or better now, but if you feel like climby climby shoot bang was getting boring, this shit doesn't reinvent the wheel.
EDIT: Looking back on this post, I apparently don't actually like this game that much. Go figure. Make up your own mind.
