Betsy Bird is my go-to blogger for picture books and middle grade books. I've ordered a bundle of books based on her reviews all the while laughing. If you join Goodreads her 4 and 5 star ratings are never a let-down.
Ben Babcock is an English teacher in the UK, I believe. I read his reviews on Goodreads. He's a tougher critic than Betsy and gives great insight into the literary process.
