I watched all thirteen episodes of Green Lantern: The Animated Series and I was astonished and dumbfounded by the lack of 'intelligence' on such a programme.
The use of the terms: GALAXY and UNIVERSE, were swapped, interchanged and used in entirely the wrong context. Especially episode 13, Hal must save the Galaxy? when Oa protects the Universe they can travel to/from. Once, a mistake, Twice, a gross oversight, but dozens of times - total ignorace of difference between Universe and Galaxy to the writers and voice actors! One or other should have picked up on the error?? We live in the Milky Way GALAXY of over 600bn solar systems and there are over 1 trillion (that can be measured Galaxies in the visible Universe). BIG difference!
