Because the show writers are the same that wrote the game, last of us has a very strong advantage. They can’t deviate from the plot and key elements because they are too invested in it. But they can change what they feel like is weaker, or wouldn’t work as well in a show format. And its really noticable if you played both the game and the show. They’ve discussed how they already planned it to be a two season series, but they also mentioned if they have enough inspiration and they can figure out a way to make a third season that stays within the spirit of the story line, and they honestly enjoy it then they will.

With the first season being as good as it was, I have complete and utter faith in them.
