Macross, Gundam, any many shows that sketchley didn't list probably fall in the category of "Ages 11 and older" or PG/PG-13 or TV-Y7-FV/TV-PG. Most elementary school kids usually don't stay up into late-night timeslots. That's for older kids and adults. Gundam is basically a 25-minute toy commercial with a story and it's predecessor in the same timeslot, Code Geass, is a little more story than most young viewers can absorb.
