I started watching this show when it started coming out and as a teenager at that time I did not appreciate the show and got bored in season 2 and stoped watching. Now the year is 2021, I start rewatching, a week later I'm caught up. The shows themes of humanity and government are very well executed but you can enjoy the show without focusing on those themes too. There's a lot of discomfort and every time I watched an episode I had weird dreams too because the horror of titans lingers with you and the show keeps you hooked. I recommend having a happy show to watch after tho.
