I can tell Nate loves Oh No! Not Again! because it frequently gets pulled off the shelf and ends up on the floor of his room after he's done reading it.
The time-traveling bespectacled girl from Oh No! is back, and this time, is in disbelief over one incorrect answer on her history test (she still got an A, mind you). Her plan to go back in time to 33,000 BCE to fabricate some cave paintings—which will render her answer correct on the test—goes completely and utterly awry.
Ridiculously clever and comedic with a slightly dreadful ending, Oh No! Not Again! has all the makings of a retro sepia-toned sci-fi film. Perfectly executed, but would we expect anything less from a team like Mac Barnett and Dan Santat?
