Sam, just give it up.
I can live with you liking the Warcraft movie (I like it too, as flawed as it is) and disliking the ending to SC2 (which I don't, especially since SC1 ended in practically the same way). I can even live with you laying every issue at the feet of Duncan Jones, nevermind that he was the one who wanted the deleted scenes kept in, and that if the film had one core problem, it was its editing and trying to cover so much, while also resorting to blatant sequel bait. But that one scene isn't some silver bullet. It doesn't tell us anything that we won't learn later on (Gul'dan shows that fel magic turns orcs green by reviving Go'el, so essentially, this is giving us the same info). Grom isn't relevant to the movie, and the scene doesn't tell us much about the core characters anyway. Now, I'm all for extended cuts (lord knows I consider the extended Lord of the Rings films to be superior to the theatrical versions), but seriously, just let it go.
Also, the Broken Shore is a battle, where characters are meant to be yelling. Most of the dialogue in the film is outside of battle, so of course they're not going to be shouting. The claim that "I could have done better" is always an eye-roller, regardless of the medium.
