Now I recently acquired the books for free, from a giveaway thing. So I read the first and enjoyed it, then I read the second and LOVED it. I simply loved the character of Dr. Levine, and the kids. I imagined parts in the book on the main screen, like when the raptor sniffs the rapper and slowly looks up, scowling. But did I see that? No. Did I even see Levine? No. Arby? No.
Don't get me wrong, it was an ok movie, but what happened? The book was awesome, and it didn't need to be changed. The saddest part is that they still grabbed characters and ideas from the book, but that's about it.
All in all, it is a decent movie. Good plot, good acting, good everything, just somewhat disappointing in my opinion.
