First of all, Jeff's review should be ignored completely. What he said makes me think that either he did it purely for the reputation and the potential gains, or he wouldn't know a video game if it came alive and slapped him in the face. Gears of War is loved by many, as can be seen by the user reviews; unlike Jeff's distasteful petty, little article.
Furthermore, the graphics is amazing - better than most Xbox One titles - and the gameplay is overall fun and competitive. This is not a reaction review, but rather a "voice of the majority" review, thus it should be known that anyone that agrees that Gears of War is worth 2/5 stars (such as Jeff), is certainly a wannabe clown; a very poor one at that.
Lastly, no review will prepare you enough for what you will experience when you play Gears, so rather just buy it and ensure that your environment is ideal - in other words, dark and quiet - before you get right into playing this legendary title. Just don't blame me if you end up playing this instead of studying or working!
