No, not nearly. Since it's so short I'd say watch it if you're a completist, but you're not missing out on much if you skip it. It's not horrible, but it's substantially "smaller" in terms of scope, character, and plot than BSG. The characters and performances aren't as good. It doesn't really know what to do with itself or know what story it wants to tell in the early episodes, and never really has time to recover. It's substantially less engaging. But at 19 episodes, it's not that much of an investment.
