Life is Strange 2 is the Super Mario Bros. 2 of the series. Good for what it is, but very different in ways that does not feel like Life is Strange. The first game made such a strong impression that it was always going to be difficult to follow up the first game, and in my opinion, they did a good job.
The major theme of the game is in how the player values the brotherly relationship, if you act moral, Daniel does too, as well as the opposite. The real theme of the game is that it only takes one thing to derail your entire life never to recover. This is a tragedy in nearly every way, no matter the decision that gets made, something terrible comes right after it. It is an exercise in how many terrible things you can witness and continue to keep going.
Gameplay-wise, there is almost no psychic activity, which keeps the gameplay a little more bland than the other games, as you can only influence rather than directly control the events of the game.
All in all, a good sequel that does not seem too related to the first game, nor the later games. This may be due to having a male protagonist or in general different themes that are more broadly political rather than simply moralistic. It is still an interesting experience that is worth having if you enjoy these types of games.
On a personal note: this game was a cathartic experience for me. At the time of playing this, I had just left a job I loved due to stress and had no idea what I was doing with my life, but this game did help me to feel things and process it positively, so for that, I will always be fond of my experience with it.
