Well, I've never really reviewed a Cinematic so I guess this is a good one to start with. The main pullback this map suffers from is the Grammar, the spelling isn't top and you've used a double full-stop here and there. I also believe that there was a few double spaces in the loading screen.
The map also suffers from, what I believe I've aptly named, Metal Gear Guard Syndrome. They see something and respond with the most gormless action possible. Try to liven the conversation points up, and don't forget to keep things real. An example of the latter is how the 3 Night Elves somehow miss the fact that the forest has been half-burnt and half covered in blight.
The cinematic makes up for this with the good use of the camera and descent use of animations, I must admit I prefer the way you've done it to the actual attack.
All in all, this Cinematic is standard. Theres points that make it good, points that make it bad. It's not as great as some of the high-achieving maps, although it's not the worst -- by far -- that I've seen.
3/5
