Short campaign - to much skiff - and... the.... (spoilers)

First of all, sorry for my english… I have play to all of the gears of war games. This one is the most short of all of them. It’s like they didn’t have more ideas, or I don’t know but it sucks. It sucks, because 2 of the 4 acts (the last act only with 2 chapters) are always with the s*** skiff. It’s to much dispersive , lack of content, The scene where you have to make a decision about who to save is pathetic. A lot of other things could happen, to make the story much more interesting. But the game developers decided to wash their hands, making you choose. As a fanatic of the gears saga, I’m really disappointed.
