eragon slow tho is nothing compared to lord of the rings slow and the movie wasn't so bad tho I'm still ticked over the 3 second make Sapphira bigger thing where it wasn't a time lapse it was some fancy magic voodoo that made her bigger 
SPOILERS (of hate)
I know what you mean about the magical 'Make Sapphira bigger' moment. My friends and I watched one of the first shows. I myself am notoriously bad at talking during movies. I think i ruined it for the 10 yr old behind me.

Anyhow the problem i had with the movie was its amazing ability to leave all things important to future plot points out of the movie. First of all, where were the twins?

Roran's Girlfriend...And why did her dad die? Isn't he supposed to cause all kinds of stuff in the second book?

I think i could go on FOREVER! on the topic of things missed or messed up in the movie. But don't let my picky hate stop anyone from enjoying the movie.
