"10 Things I Hate About You" (7 p.m. Central Monday on ABC Family, one hour)
On air: 2009-10, one season
Why it was great: For some reason, traditional sitcom humor works for me only if it's teenagers delivering the lines. When it's adults, it all seems so juvenile. There's something likable about teens who are quick with a quip yet also trapped in a high school setting (which can be absurd without sacrificing reality).
