For example, a couple of years ago I watched the first episode of Boku no Hero Academia. As soon as I finished it, I quitted because it was so slow, so obvious, no wit, no charm and it was so repetitive.
The same year I watched the first episode of One Punch Man after watching a review about “how deep and good the show is”. But it was very boring and it had a purple guy with the face of a Dragon ball character in a goofy underwear. Not only the first episode didn’t match with the expectations that the review created, but I also realized that action films or shows are not my thing anymore. They have the same music, the same punches and the same silly designs.
At least shows like Six Feet Under and Succession have really good first episodes.
