if it turns into yet another action fest adrenaline on steriods rollercoaster without much human element. GAme movies have almost unanimously taken that approach, and they've sucked. Because fantasy and science fiction are so out of this world to a lot new viewers, they lose interest if they can't connect to anything strongly and a very identifiable human element is able to be related too.
Take the original star wars - what made those 3 moveis stand out to so many that came out after it? you had a mini love story going on, and some real tongue in cheek humour everyone could identify with. What is missing in almost every action moview based on a video game?> exactly that. Take the newer star wars movies. The action was really good, but no tongue in cheek humour, and the love story came across really weird, hardly natural. Which may have been the plan but you do need somethign good.
Now look at a very wellbalanced movie, Lord of the Rings, intertwined in teh epic struggle, you have realness in something small can affect something big, despite all the massive forces around with their very real power still the biggest battle is fought in the hearts and minds of men, and yes altho it was hobbits, everyone can relate to their struggle Even the perfect elves you can relate too, yet apprecaite them for being different. Intertwined in it was a love story, that came off quite well. I'm not saying the bookfs or films are the best story ever written, but the blaance was very sweet, and the moview captured and displayed that essence well
So, fo a warcraft movie to be good, you have to have all those elements, against a stunning visual background which we know exists in teh universe. Teldrassil ffs, an entire country size wise in a tree, then the dwarves in their mountains, the blood /high elves in their strange magical wonders. the diverse landascape from exotically beautiful purples, silver and pink Ashenval and nighte elven forests to the golden beauty of Quel 'thalas, - lush verdant forests PAnderia, jungles of strnagle thorns, crsytal ice waste of northrend - that's almost the easy part, it's a well balanced story though that despite all the alien looking creatures like Tauren, Orcs, Trolls etc, people can very much relate too that would make this a hit and buck the trend of disappointing video game movies
