I didn't finish watching Boku no Hero and Nanatsu no Taizai, although I read their endings, simply because, halfway through, I didn't feel the same excitement, and why? I felt that the plot was falling flat or that I was expecting something more. I didn't like the endings, and even less so the development and how they handled it. For me, the fights weren't as exciting anymore, and the plot, shortly before the end, seemed boring and mediocre. There wasn't as much creativity, and the story became predictable or unadventurous. I know there are people who like it, and that's respected, but in my case, I couldn't continue without something else catching my attention.
