Hmmm...well...there are a lot of movie sequels to choose from...Its hard to pic.
I loved the sequels to Narnia, Lord of the Rings, Fast and Furious, Step Up...(theres more on this list...however I don't feel like sitting here all day ticking them off my long list of favorite movies)
its not that one is better than the other, but that they seem to grow as they go along. They develope more. And that is really interesting to watch. So I wouldn't say I like one sequel better than another. They are all good.
