I found the first two books engaging and fun to read; enjoyed the final one less for reasons some people have already commented on, though not to the point that I had to force myself to finish, just had to push through certain slow or filler sections. The best book imho was the prequel - the ballad of songbirds and snakes. She really did a great job of tricking you into routing for character development from a character you know doesn’t develop in that way.

Ultimately I think some people work too hard to dismiss popular fiction because it’s popular or easier to read.
