Ok I deleted my first reply, but I must say there is no need for the personal insult, I have not insulted anybody here for liking this movie, so there is no need for the suggestion that I might be stupid because I found the Jargon to be way over the top.
Yes Lord of the Rings has stuff like Gimli son of Gloin, Gandalf the Grey, but they are words used in the English language that are not too hard to work out what they mean, you know like Gimli has a dad called Gloin, or the Gandalf wears grey. However we have to have this drawn out scene to explain that Mars is called Barsoom and Earth is called Jarsoom, and that he came from Earth to Mars, something we were already fully aware of, rather than getting on with the main plot of him helping to rescue Heliumites from the evil clutches of the Zodangans (Thank you Disney Wiki)
