First of all let's go to the graphics. Machinima called them beautiful and ReviewsOnTheRun said that the enemies looked the best of any game in the franchise.
For story, nothing is spectacular. The new character Sofia is cool but Baird can be really unlikable. However the end is interesting as it points to the first Gears.
The gameplay is great as Strategy Informer said the campaign is only 6-7 hours and the last few levels are very linear and tedious. As IGN Italy said the multiplayer was fun and enthralling but could have used more modes.
Overall get this game if you want to. It's not amazing but it's not a disappointment.
Gears Of War Judgement is rated M.
