I'm... surprised to report I actually liked it?
I didn't think I'd continue reading this series, the first book being what it is. But I wanted something silly and fun, and was surprised that this actually had a plot? And a relationship between David and Amy? And plenty of the fun stuff from the first book.
Now I'm definitely going to read the next one as well. If you're on the fence about this series - skip the first book, start with this one.
