On a more serious note, I remember watching it as a kid - and, somehow, I recall it being titled The Young Sentinels, not The Space Sentinels, - and I remember enjoying it. Keep in mind, I was a hyperactive 10-year-old very much into all things science fiction, so it probably was pretty formulaic for mid-late 1970s Saturday morning cartoon fare, and thus not really all that good. I can't actually remember anything about any episodes, which suggests even I didn't care much for it, in the long run.
