Not bad...
Dialogue was great, but only to be expected. Scientific accuracy floating somewhere around the Irwin Allen level, with among other things terms like "galaxy" and "solar system" grossly misused, which kind of sucks. What are they teaching kids in these schools nowadays?
If I see one more background shot of gigantic planets floating in the sky like a pile of basketballs, I'm gonna hurl. Anyone ever hear about tides out there?
