Jak 2 was a pretty awful game, deal with it folks. People who enjoy it are simply masochists.
They took what was a fantastic mario 64 knock off and decided the colorful fun world they had created would work much better if it was bleak, dark , bland and filthy. Then they gave their silent protagonist a voice and made him angry and obnoxious, threw him in this same terrible bleak unhappy world and filled it with unfun missions, timed racing levels , no checkpoints and just generally I don't think anyone at naughty dog actually playtested the game before it came out. I'm really not sure who it was built for- almost as though GTA3 and devil may cry came out and ND said, hey these are kind of cool, let's make 75% of our new game rip off these ideas instead of simply making a proper sequel to jak 1, instead of using this interesting world let's make it dark and stupid because kids don't like fun these days.
I imagine my problems with the game largely stem from my age though, I grew up in the era where games were either fun or they weren't, had I been born 10 years later I might have been lead to believe that pointless gimmickry and 90's level "bad ass itude" were replacement for good , fun gameplay but sadly I just can't bring myself to enjoy games that aren't fun.
Uncharted is just all around a MUCH better series. I'll agree it's hardly the most interesting or original bunch of ideas but for the most part the uncharted games are fun games that are also pretty to look at. I can agree with the OP there, The Last of us does indeed look like someone REALLY liked the walking dead and thought, hey why don't we take the walking dead and mix it with classic survival horror elements as well as the uncharted engine ? Undoubtedly it'll work wonders.
I kind of wish ND would take a small break and take another stab at a character /cartoon action game though. Especially now that Ratchet and clank seems to be be pretty well finished.
- in short - the OP raises a valid point but perhaps does it with a bit too much flame baiting
