I wish they had done the Arthas story line. They could have split it into 2 movies Warcraft:The Frozen Throne with the WOTLK cinematic as the ending scene and then part 2 'Warcraft:Wrath of the Lich King"
Hopefully the movie doesnt bomb so we can see that happen...
I disagree. Arthas story line is even more convoluted. They would need to introduce too many things at once, which was already a problem in this one. They would need to properly introduce demons, the scourge, elves (due to Sunwell scenes) among other things.
Arthas story is one of my favorites, but the universe must be well established before it can be told.
