As AYB has suggested, "Snow White" is certainly encroaching on LoTR territory, and lacks the scal toe back it up. That's not to say there isn't some nice imagery to be seen from the trailer, but if you're going to ape Tolkein, you should go all the way.
Now, in regards to K-stew: I don't hate her as much as other people seem to--she has annoying tendencies, but nothing about her is god-awful. With that said, I'm less than impressed with what I've seen of her thus far. This should be the movie that changes the public perception of Stewart, a complete role-reversal from the more passive Bella from Twilight. Instead, the trailer hides her behind Hemsorth and Theron (who seems to be the only one who realizes how ridiculous this film is, and may be the reason why I bother to watch it), mainly because I don't think she can sell a movie like this.
Maybe I'm wrong, and this turns out to be the "Red Steel" of this summer--but I wouldn't hold my breath.
Red Steel, the Wii game?
I think the mo9vie is trying top be LOTR, but to me looks more like it's going to be more like the Narnia movies n tone, and I'm pretty sure the Narnia books pre-date the LOTR books by a couple of years (correct me if I'm wrong though)
I gotta say, I love the visuals in the trailer, things like the way the queens knights shatter, it's clearly a way to keep the movie PG 13 but it's very cool.
