I was wondering who Alodi was. The first guardian eh? They should have just made it Aegwinn, as that's who they apparently intended it to be.
I've been thinking some more about what this movie could have done better. The main thing I think is the (male) orcs. They really should have made them more human looking. Look at the LoTR/Hobbit movies. Most of the dwarves in those movies don't really look like Tolkien describes them, but for a live action movie they actually look better. Also I never played WC3, but I've looked at some of the cinematics on youtube and the orcs there look far more human than the orcs in the movie.
Should they have just gotten some bodybuilders and slapped some green paint on them a la the 1980s Incredible Hulk TV series? Probably not, but if they had made them more human proportioned they would have looked better I think and they could have reduced the reliance of CGI (which still has its limitations).
