Fair review with spoilers extending to what you'd see in a commercial.

Rating: 9/10 (10 June 2016)

First and foremost, I'd like to thank the critics (rotten tomatoes) for helping me determine whether to see the movie. I know that they have terrible taste in movies so if they give it a low rating then I can count on it being a good movie since movies tend to turn out opposite of what they rate it.
Next, I'm going to list the pros and cons for this movie so the average movie goer can get a more accurate depiction of the movie.
For the average movie goer, the CGI tends to stand out the most among the experience. Even the magic, which can easily be boring such as the Harry Potter movie with the scene involving the duel between Voldemort and Harry, was up to par. The magic looked impressive as it should be. The fight scenes were well choreographed so if you're an action junkie and love a good fight scene, then this will not disappoint.
Warcraft lore is packed with so much information that it isn't feasible to get a non-fan up to speed in just one movie. The movie's story line is more of a summary of the events that transpired within the World of Warcraft. All of the main characters have significant back stories and so do the locales. For example, Khadgar travels to Dalaran but the significance of that place has not been explained. Therefore, only the fan base knows why it is flying in the air or why Khadgar travelled there in the first place. The non-fan would only come to the conclusion that powerful mages reside there.
The relationships were not explained in detail either. Orgrim and Durotan are best friends and when Orgrim betrays Durotan, a lot of the inner turmoil Orgrim faced before making that decision had been left out. He just "happened to do it".
If you are a fan, you will love this movie. I spent the entire time examining the architecture and looking for details that correlate to the game. A lot of us raided Karazhan in BC so it was cool to see how much of it looked like the movie version. Even Moroes, who was a raid boss in Karazhan, had been featured in the movie, along with his death. Stormwind and Ironforge were wonderfully crafted and look like the in-game version. Practically, every visual detail had been pushed to perfection, in regards to precision.
Then, you have a bunch of characters who were not introduced but as an avid player, would be able to recognize. Among them, Grommash Hellscream and Kargath Bladefist are shown on screen and easily recognizable. The characters look like their in-game counter parts and that was impressive.
As a fan, my complaints are as follows; does a mediocre (at best) job at drawing in non-fans, cheesy/cliché dialogue which makes the characters harder to relate to since they don't display normal personality characteristics, and a weak lead in to a sequel.
TL;DR version
Good CGI and fight scenes to make it a visually impressive spectacle for fans and non-fans alike. Underdeveloped story line leaving non- fans confused about each character's plight and motives. To be fair though, the Warcraft Universe has so much story in it that it would be hard to fill in an uninformed audience in such a short amount of time. Literally, to capture all the backstory leading up to the events in the movie would take up an entire movie slot on its own. Ultimately, a non-fan would have a general idea of what's going on but would not be able to appreciate the accuracy of architecture and character models since this would be their first time experiencing these elements.
