Just finished watching this, I haven't played the game. This was a good one, but not as good as it was hyped. Overall the plot was good, but it felt too much like a console game when it comes to plot structure. Like there was a sequence of discussions, followed by an action scene. Something I would expect in a console game, but not in a tv shows. But I also understand if they wanted to follow the plot of the game.
One thing I noticed: Ellie saw Mortal Kombat II game in one of the first episodes, I think she said something like "I've heard this was a good game". Then later on it's shown that she played it in the mall before she was bitten. A script mistake or did I just misheard that one?
