1. I disliked reading a Harry Potter story as a play. I don't mind reading plays, but after the previous books my mind is trained to digest Potter stories through the novel form.
2. There was a lack of depth in terms of the characters both new and old. I didn't feel connected to anyone and the things I loved about the characters before was absent.
3. Part one was better than part two; the second installment was incredibly rushed, contrived, and mediocre. I thought the idea of time travel and simply dipping back in to scenes from the other books was a little cheap.
4. The normal charm and whimsy was absent. My heart was not warmed and my mind was not intrigued.
5. I had low and realistic expectations, though, so I don't feel angry. I knew going into the story that it was a play and that it was the result of a collaborative writing process, so I was hesitant to have high hopes. It wasn't horrible or a mess, it just simply was not good. Rowling set the bar high with her other books, and Harry Potter and the Cursed Child simply did not rise to the occasion. I do have a sneaking suspicion that the play would be a lot of fun to see, though, since the actors and set will probably add a great deal to what is lacking here.
