David Cassidy and half-brother Patrick Cassidy camping around in fake MTV videos looking like Duran Duran and singing a fake synthesizer-heavy song called “Chunnel of Love’’?
No, you’re not in the grip of an ugly postmodern flashback, with the 1970s and 1980s merging into some kind of spandex nightmare. You’re on a new ABC Family sitcom called “Ruby & the Rockits’’ that has no right to be as likable as it is. The show, which premieres tonight at 8:30, seems like its going to be a “Hannah Montana’’-type thing, with Alexa Vega (“Spy Kids’’) as the musical Ruby and David Cassidy as her single father. But “Ruby & the Rockits’’ turns out to be a warm intergenerational comedy that never pushes life lessons in your face. The scripts are made of familiar parent-child ribbing and hugging, but they’re given a nice buoyancy by all involved.
