Hey Pandas, What's Your Controversial Opinion On A Popular Book Series?

I don't see people talking about this much but The Selection series was only good until The Heir book, then it took a turn into incredibly boring. I really enjoyed hungar games and Divergent and I think Katniss and Tris were really interesting characters except for the last books of those series which I had to force myself to finish. Also I love Twilight, the movies are terrible but the books are fun and filled with diolague, maybe not the best written love story in the world but I found it to be a light and enjoyable read.
