As a huge fan of the game franchise, the first few episodes are a disappointment of course!
First thing, it's an adaptation, so characters and story may, to some extent, be different..
At first it's good, the atmosphere, the ost, the actors and the acting, even the cgi is great..
There are even some scene that are really similar to the game. So everything is here... Everything? no...
They removed one of the gameplay feature and major story point, the spores... No mask needed as far as it goes for now...
The other thing that bothered me was how all clothes are freaking new, not even dirty, just plain new, after 20 years smuggling shit in and out a QZ.. LOL!
But to be honest, these games really touched me, and one of the reason is Ellie, as she is, not as an over-weighted child with an emotionless face! Sadly, all scenes packed of emotion from the game were Ellie is involve doesn't work at all in this adaptation.
Ellie is, I think, the worst cast ever made, even more than the "uncharted" movie ! And with all the actor there are, it is a shame!
Without this horrible mistake, it would have been the best video game adaptation ever made !!
