Season One was critcally acclaimed almost across the board. Personally I thought it was pretty good although a couple of episodes the pacing was slow, and one particular episode the plot had little to do with the overall storyline. If you saw Season One you can guess which episode I am talking about.
Season Two has started off with a real bang and I look forward to it every Sunday. Sure, it is very much like The Walking Dead (I watched all 11 seasons of that and every spinoff show), but TLoU zombies have a new and terrifying twist and the acting is absolutely top notch!
