You need to give the story more effort, and watch the actual episodes the shit on KZfaq is just clipped to all hell. Your missing like 80% of the story and the meaning behind each episode

This scene is badly clipped and from near the end of the season. If I saw this video before watching the show I'd probably think it's boring too.

You're possibly one of the MHA crowd that need the high octane action to maintain your interest. If that sounds right, then I suggest giving Frueren a try in about five years after you have experienced more in life. The series has those fast paced action scenes, sure. Stark and Fern are both flashy like that. But I much prefer the fight that was won before it even began. The fight so one sided that the series took an entire episode to explain just how stupid the enemy was to challenge Frieren. How stupid was it? It earned the coldest line of dialogue ever uttered in Anime.
