Review: Five Go Gluten Free by Enid Blyton (text by Bruno Vincent)
This one is what it is, and it's great fun so long as you go in looking for a few laughs and nothing more. The pictures provide a lovely bit of satire, and other beloved characters from the series find themselves the butt of various jokes--I loved Uncle Quentin's car, which runs on peanuts and could explode at any moment. It never quite meets the benchmark for Famous Five parodies that was set by The Comic Strip Presents in the 1980s, but there are some great moments.
Not a classic, but lots of fun.
Recommended to grown up fans of the Famous Five.
