Let me be straight with you. At the time of writing this, I feel ill, and so I'm not going to be all wishy washy about how I review this stinker of a book.
This book suffers from many things: 1. You can tell the authors tried for a plot, but they really couldn't have done much worse trying to make believable, likable main characters. Now I know that may seem difficult as they all have powers besides our annoying little big head, Kid Normal, but still.
2. The plot. Any movie, particularly a superhero movie, would benefit from a similar plot, but that is when you exclude certain aspects. The villain is cheesy, but then again, you would expect that from a kids book, but also, the plot is extremely overcomplicated. It may not seem it when you start reading, or when you are half way through, or even when you have finished it, but when you look back at it, you will see the truth in my harsh words.
3. The humour. I already mentioned that it was cheesy, but this is one aspect where it does well but simultaneously flops. How our main hero, KN gets into this "super school(?)" is funny, but other moments, such as the headteacher's name, "Mr Souperman" really flops, at least to me.
The end.
(Btw, the other books of this series are a bit better, so it might be worth suffering through this book to get to them, your call.)
Now this is truly the end. Bye bye.
