Some footage got leaked, watched 4 minutes of it.
This is 100% non-canon.
Durotan, Orgrim and many other orcs aren't green.
Guldan opens the Portal by himself.
The Portal leads straight to Azeroth instead of being "a bridge between worlds".
Female Orcs are too cute, Garona is just their version of Marvel's Gamora.
etc
So yeah, this is not "WarCraft" I wanted to see all these years. Still interesting tho.
In terms of visuals and animation it's not realistic but on par with WoW cinematics, which is good enough.
