What’s striking is the degree to which the material remains essentially unchanged.

“Blue’s Big City Adventure,” from the director Matt Stawski, is a feature-length adaptation of “Blue’s Clues & You!,” in which Blue and her human companion, Josh (Josh Dela Cruz), travel from the colorful 2D confines of so-called Storybook World to the madcap streets of real-life New York City. While this is a worthy cause, it’s hard to imagine how the format might translate to the big screen. It’s designed to subtly and enjoyably help kids practice and deepen their reasoning abilities - the series co-creator Angela Santomero has said that she intended to make “a show that would help preschoolers feel good about themselves.” The dog, Blue, helps the host solve mysteries, and the audience is encouraged to participate in the fun by shouting answers at the screen. It’s a modern revival of a show from the 1990s, “Blue’s Clues,” which was about the same dog, but which had a different live-action host.

“Blue’s Clues & You!” is an educational program for preschool-aged children about a friendly cartoon dog.
