B-
It's good, but barely.
The bad things:
1) Kristen Stewart. She wasn't terrible, but I couldn't ever get a good read from her. Which takes me to point two:
2) Who the hell is Snow White? I understand she's pure, she's life itself, all that bullshit said about her. I wanted to KNOW her. The movie didn't properly make her a character. This was both due to Kristen Stewart's performance but also the script. The script kept telling us about her character rather than you know...actually making one. This meant that when the movie ended and she was crowned queen, it didn't have the impact it was supposed to have. I didn't leave the theater excited and my heart pumping. I was more like "Eh, she can't be any worse than the Evil Queen." For the record, the Evil Queen wasn't developed much as a character other than she's evil and obsessed with beauty/youth but I still wanted her defeated so not that major of a problem.
3) Worst inspirational speech before a battle ever. This was only minimal on Kristen Stewart since I don't think even Meryl Streep and other actresses of that caliber could have made it work. It felt more like she was trying to get people to grudgingly follow her and not die to make her queen. That speech was just terrible.
4) The movie didn't properly develop the relationship between the Huntsman and Snow White. Considering that's what the movie's title is about, this is a big problem. It should have taken less time with the Prince Charming character and the Queen scenes and more time showing us the Huntsman and Snow get closer. The movie tried for a Han Solo-Leia kind of relationship but failed because it didn't take the time to actually make it work.
5) What were the rules of magic? Why didn't the Evil Queen's magic work in the Dark Forest? Why show us why she has her youth spell but not her other magic spells? The movie didn't properly develop it's world.
In essence, the problem with the movie was it just had stuff happened without any rules and without bothering to make us care. On the other hand, the cool stuff that happened was pretty cool and Chris Hemsworth was entertaining as he tried to mimic Harrison Ford. It was entertaining enough, although it dragged in some places-places where the movie could have better developed it's characters, world, and relationships. I enjoyed this movie despite it's flaws but I felt that if it had a better script and a different lead, this could have been a much better movie.
