I feel like this show might be doomed once they adapt Part 2. Like it won't be cancelled or anything, but I can see viewership falling off. TLOU2 doesn't have as many high note moments as TLOU1, and it also lacks that mainstream appeal. It's going to be a metric ton of dialogue and slow scenes, half of which are going to be from characters that the audience will hate. This isn't going to be like Game of Thrones when Ned or Robb died, because you still had a lot of other great characters and storylines to follow.
Not to mention it's going to open up Pandora's Box again, and the culture wars surrounding Part 2 will be back in full swing. I'm not looking forward to it. I might actually not bother watching. I was hoping that the adaptation of Part 1 would be so good it would surpass the game, and then maybe I'd be interested in the idea of a better version of Part 2. But so far while I like the show a lot, it's not better than the game. One thing's for sure. In 2-3 year when Season 2 is out, it's going to be a hateful and miserable experience all around.
