I really hate to give anything about Harry Potter less than five stars but I have to this time. It was probably more the fact that I was reading a play versus a novel that just didn't do it for me. I just didn't get that sense of being lost in another world. When I read the other Harry Potter books, whether it's the first time or the fiftieth time, I get lost in the world Rowling has created. I just didn't get that feeling this time around.
I also had issue with the story. It was pretty much your run of the mill time travel story. One of the best things about Harry Potter, was the originality of it all. This just didn't feel like anything special to me.
Maybe if I were to see the play in action sometime, I might find myself feeling differently.
