I was highly impressed by The Last Of Us games (1 & 2) but not enjoying that much from the series.

So I believe if you're a fan of the games, it might happen to you as well. You won't be impressed by the series because of two reasons:

1. You know the story.

2. Characters in the games are far more charismatic.

Pedro Pascal is so so. Bella Ramsey is not a really good choice for Ellie.

But if you've not played the games, it can be a fantastic experience. The original game has a perfect story and chemistry. And it seems like the series is gonna deliver the same feeling. It's actually the most valuable aspect of the series.

It adapts the game very well.
