Eragon is utter garbage, like the movie. It's written by a 17 year old and it shows. I had to turn the movie off after 20 minutes I couldn't bear the endless cliches and pathetic script. If you're 10, then all right. But if you're 10, you should be reading Harry Potter.
Yeah, read GRRM. As for him splitting crows/dance up. It doesn't really make much sense. It's not like the threads are tied up for the characters in crows either. He really shoulda just wrote the entire book and then cut it in half. What makes even less sense is that if he had most of it done, how come he's taking so long to write Dance with Dragons? I think he's just stalling for time and he doesn't really know how to end it. The fame is getting to his head. I guess that's one problem of killing off every other person. Meanwhile, he has all this time to write other books and stuff.
If you want something quick and not utter garbage, read Feist's first set the riftwar saga. Ignore his other books like the plague.
