@Blyss There is no way the negatives are outweighing to positives when it comes to var so far. The refs aren't going to look at the footage with every single faul, that would be unreasonable. It's a completely new system, we need to give it time. Also, it's not as if people weren't already overreacting as soon as they got touched.
About the penalty, Bas Nijhuis (a fifa/uefa ref) said that his hands were not in a natural position roughly next to his body and therefore you can in fact give a penalty. Which i find totally reasonable. Cedric SAW the ball coming directly towards him and lifted his arms up anyways. He only turns his head away when the ball is 40 cm ish away from him so it's not as if he didnt see the ball coming. You do not only give penalties when it's a deliberate act of handling the ball, you are not supposed to swing your arms around like that, especially in the penalty area. You know the risk. Grey area nonetheless.
