The physically impossible part wasn't the biggest problem, it just happened to be very noticable (there is no way those barrels would stay upright while going through very turbulent waters like they were). The scene was already good in the book. It was not an action scene, and doesn't need to be, but jackson seems to hate not having constant action. Its just an annoyance, but its one of the scenes that sticks out in the book, and seeing it turned into some kind of action fest just struck me as being stupid. Also, I'm not "moving on" to the Hobbit. I love LOTR, the books and the movies. I liked the first Hobbit, despite its flaws. I'm excited for Hobbit 2, even with some of the weird stuff. That said, I am going to talk about the weird stuff, but this is a totally different situation than with MoS. That doesn't mkae this movie immune to criticism, but I'm not looking at this movie in a negative mood, I'm just talking about it. I'm sure I'll enjoy it when it comes out, but until then if I see something weird, I will probably mention it.
