I watched it on the 8th, thought it was decent. I had high hopes and while it's not THE BEST, it is definitely not the worst. Some things I liked about it were how badass the action was, the magic, and the lore (Which it stays true to most of the time). The portal scene in the beginning was also really, really amazing.
EDIT: Also, the box office numbers are looking really good right now, so hopefully we get a sequel with either Illadin or Arthas in the future, though the next movie will likely be about Thrall/Go'el.
