To the disheartening of many fans of the book series, men in ties decide to make a dragon movie without any dragons in it and decide the story is too confusing so they just remade Star Wars. Beware the powers of the dark side of jelly beans!
If you're like us and have never read the Eragon book series, then you'll arguably have less problems with the divergence (that wasn't an accident) of the source material from the pre-teen books to this flaming pile of nonsense. It's a necessary position to look at the 2006 film objectively. We don't know the back story and the subtle elements of the world that this takes place in (if there are any) so don't come at us, bro! And in any situation, none of that should matter - because Eragon the movie, at least, doesn't suffer from it's abandonment from the source material - it suffers from the direct theft of OTHER source material.
It's just Star Wars gang. Which may seem like an oversimplification of the standard "epic" format of storytelling, ie. Star Wars, Gilgamesh, LOTR, The Iliad and The Odyssey, et. al. we can show you that it is a direct case of intellectual property theft or the great scene heist of 2006. Perhaps the writing team called in Danny Ocean...

Try to argue that against us kids.
In the end, Eragon isn't a great bad movie, but it's uncanny rip-off of that space wizards movie makes it a great time for riffing. So it's a do.
