I watched... I have no idea what to say as I don't have or know any pre-schoolers.

I usually dislike "back in my day" comments, but when I was a pre-schooler I watched TNG. Did I understand anything? Not at all. Did it instill a lifelong love of the franchise? Possibly.

Prodigy was an excellent show, I guess it's also "for kids" but older ones, I thoroughly enjoyed it as an adult. Scouts, from what I can tell from those 8 bizarre minutes, is more at the level of Discovery in terms of quality of writing.
