Lighten up, guys! It's an enjoyable romp. The animation is out of this world, and the action is heart-pounding.
All this talk about retcons and canon reminds me of a line from the theme song for Mystery Science Theater 3000: "Repeat to yourself, 'It's just a show. I should really just relax'."
Show me a man who is twenty and not a liberal, and I will show you a man with no heart.
Show me a man who is forty and not a conservative, and I will show you a man with no brain.
