Note: I skipped 400 days and michonne
TLDR: All 4 seasons are amazing, I'd recommend them to anyone.
Season 1: Great introduction to the series, at first it felt a bit odd that walkers just appeared out of nowhere (im unsure if this is explained and it's just something I missed) but besides that it was amazing, Lee is an amazing character. Although just meeting clementine he still knew he had to do everything in his power to defend her no matter what just because it was the right thing to do. His overall dynamics with every character are amazing, he truly has hope in people and always tries to do the right thing to unsure everyone's survival no matter the cost (saving Larry, helping Ben, saving clementine as a last act of his life). His death was emotional, i personally chose to have clementine to shoot him since I see it as his finale lesson to her. Sometimes you need to let go.
Season 2: Seeing Clementine picking herself back up after Lee's death was interesting. Omid and Christa didn't last long sadly but atleast we got introduced to a whole new group soon after, clementine 'proving herself' and the 'I'm still not bitten' line is still so cold imo. When Craver finds them it was really cool to see Kenny again (although I have no idea how he survived in ep 5) I don't understand why people in game and in the community think Kenny was 'bad' or 'unstable' he's someone trying to pick pieces back up after losing almost everything. Some pain is impossible to hide even if you let it out on people who don't deserve it. I hate Jane for trying to 'prove a point' by acting like she got AJ killed as If doing that logistically proves anything. Kenny couldn't be alone i ended off with him, season 2 was probably my least favourite season but it is in no way bad.
Season 3: Javier Garcia was a very interesting character, having to choose his loyalties consistently and being so quick to trust clementine and killing in order to protect her was a very interesting take on a character. It shows us human kindness exists even with dangerous groups of people being present in the world. Playing as Javier was fun sad that we never got any more of him.
Season 4: The season 1 parallels and seeing Clementine needing to step up and lead Ericson's towards survival was amazing. I see so many people hating on this season because it had to be rushed since it was right in the middle of telltale's conclusion but that still doesn't take away from how amazing it actually is. Clementine and AJ' dynamic is amazing, trying to teach someone what's right and wrong in a world where most people barely consider it is an amazing plot in my opinion, it shows people's hope for the world to be better hence why they still have morals and choose to share those morals to others. This season probably had the best side characters
Final verdict: This is telltale's greatest project by far, this game had me invested from start to finish, the greatest feeling I get from any media is the regret of not consuming it earlier which is all I felt during my playthrough lol. This game is a top recommendation for anyone. Thank you for reading, God bless.
