Dragon Ball Z: Battle of Gods

How are people praising this movie? it has awful writing, awful pacing, and an awful ending. I think nostalgia is getting in the way of good judgment. It clearly shows that they were making things up along the way since most of this stuff makes no sense. The animation is OK for the most part but some of the 3D stuff just does not work. Bills is considered to be a villain but he's hardly threatening at all. How are we supposed to be scared of him when he acts so petty and childish while he's on earth with the Z fighters? Who are once again, just like in GT, all rendered absolutely useless. Kinda like the writers of this movie.
