I'm a big fan of the original Dragons Love Tacos! It's a great read for kids in that it's quick and engaging, naturally I thought the sequel would be more of the same.
Personally I thought the creative team phoned it in on this one, the illustrations are clearly not as detailed as its predecessor, instead it seems Daniel Salmieri went for more of a "crayon look" that comes across as much less refined. The Author also didn't seem interested in working too hard on the story, the sequel seems to recycle the good parts of the original and then sort of sputter about for a few pages.
Children's books are harder to make than they look, and it looks like this creative team put this together over the weekend. I'm sure kids will find it entertaining, but as an adult reading this to his kid, I feel like it's fair to ask for more.
