PARTIAL SPOILERS!
There are so many amazing things to say about this show but first I want to focus on the negatives.
Many of the one-star reviews are because they didn't see enough zombies and the story is cliche. The theme of this show isn't horror or thriller, it's a drama. It's not supposed to have horror zombies every two seconds. I personally feel like the use of the Infected was very well done. They used them to climax the episodes and didn't overkill them.
Now, before you call me a bigot or a homophobic person, please know that I am NOT! However, the third episode I felt was completely unnecessary. The love story between Bill and Frank could have been shortened drastically. The episode had nothing to do with the actual storyline at all besides the fact Ellie finds a gun.
Overall, I am a massive fan of the video game and yes, that does make me partially biased but to see how they made certain scenes like the video game (like Sarah in the truck or Joel sniping the Infected) made it so much better for fans of the video game.
