I didn't play through all the map, but I'll give a review based on the furthest I got.
Atmosphere - 1/5, although the terrain seemed 'Blizzardy' enough, there were some bad bits, especially near the shores of water, the UI was the same-old-same-old, however the thing that really got me is the loading screen. Now I'd tolerate some artisticness, but that's a freaking cartoon porn that has nothing to do with the campaign aside from including Kael and Vashj.
Gameplay - 3/5, it doesn't attempt to do 'too much', sticking to the old Wc3 style, which is known to work. However, the abilities definitely needed more originality.
Fun - 2/5, you should include more base-building, I mean, it's Wc3 for god's sakes. Apart from that, it was average.
Storyline - 2/5, kinda gay, how Tyrande just says 'Lets revive him'. Really? And how did they encounter Maiev? She is trapped in Outland and possibly killed, play TFT again.
Cinematics - 2/5, there are like 3 in a row in the beginning. And the cameras isn't that good. In the level where they first meet Maiev, the camera when following Vashj goes through a heap of trees. Also, the dialogue is lacking; 'Lets go, CMON!!!'
Overall - 10/25 = 2/5. It needs alot of improvement. I shall not vote as of yet.
