Ok guys, I just want to say something.
No matter what you do, it's impossible to please everyone.
For example, LOTR movies are considered a masterpiece by most of us, but I know a lot of people who don't like them, whether because they are too long, or because they don't like the Fantasy genre and only watch realistic movies.
Critics gave 8-9/10 to films like Gravity and Cabin In The Woods, but to me they are some of the worst movies I've ever seen in my life, and trust me, I've seen a lot.
Everyone loves Skyrim, but I don't. I found it so boring that I couldn't even finish the main storyline (and yes, I know there are mods).
A band releases a new album? Some people will say it's the best ever made while others will bash it saying it's shit because it's not as good as the previous ones.
... I could go on with more examples for days.
Eventually you need to understand that it's all subjective. There is always going to be someone that likes what others don't, and vice versa. If you didn't like the Warcraft movie that's fine, everyone is free to have their own taste. But I wouldn't call it a failure, it's already the
4th highest grossing video game movie of all times and will probably get to #1 by the time it exits theaters. It's also the video game movie with the highest audience score on IMDB, Metacritic and Rotten Tomatoes. And before you call fanboys, remember that every franchise has them (check out the 10s of BvS, Civil War or any other superhero movie on IMDB) and that there are also lots of haters (they actually started to give Warcraft 1 before fanboys gave it 10). Actually, the more something is popular, the more haters it has.
