I've just watched some of the Rebels stuff on youtube. First I'd seen of any of it, and it's a bit more frivolous and silly than I was expecting. I've just read John Jackson Miller's novel A New Dawn, which features Kanan and Hera a while before the beginning of the TV series. It has some smartass dialogue from Kanan, but the overall feel is a lot less, well, cartoonish. It's a big mix of political and corporate machinations, conspiracies, people who aren't who they seem to be, people working their way through difficult moral situations, and a lot of 1977-style adventure and fun, too. Not to mention chases, fights, and explosions. I really liked it. The Rebels bits and pieces I saw don't really capture that. I'll give it a shot, though, because A New Dawn was apparently developed with the people working on the show (that new canon thing) and may be an indicator of the kind of depth the TV series may eventually be capable of.
