Finished the game last night..
One of the problems with the Uncharted series in general is that in grounding the series is somewhat realistic settings, you can't have a big Doom-Cyberdemon style boss fight at the end. Even though Lazarevic was semi-immortal, it would have been lame to just shoot him a bunch. The resin idea wasn't bad, although I think it would have been way cooler if they had factored the living tree into it. I mean they showed that the roots could move and the tree crushing buildings in the end. It would have been awesome if the tree had been actively fighting at the end (since you did light a fire under its ass). So in a combination of gunfire and traversal, you escape the area while the tree rips Lazarevic apart or something.
I felt that the bridge scene and saving Chloe and the final dialog were all well done, but I was a little dissapointed that after having an awesome set up for the Cintemani stone, it ends up being a red herring and all of a sudden they're trying to bring closure to all the previous story elements (The stone is resin!, The black teeth are caused by eating the sap! Which makes you go crazy!??) Eh.
Like Lost, the setup is better than the pay-off.
Still, one of the best games I've ever played
