Daly is ideal as the principal who loves his rules and his No. 1 certificates for being first in the state's achievement tests (hilariously called the B.L.A.A.R). Parks and Recreation vet Retta co-stars as his devoted assistant principal, who -- like her beloved boss -- believes you should "teach to the test, not the students." (Um, nope.) Riggle makes the most out of playing Carl, Rafe's soon-to-be stepdad, who pretends he cares about the kids in front of their mom but really wants them out of the way. The light romance and rebellion make this a better fit for tweens and actual middle schoolers rather than really young kids, as does a poignant plot point that explains a lot of Rafe's behavior.
