There is always going to be the element of human error involved. Even if Toronto reviews more plays, people will still come up with conspiracy theories when the calls don't go their way. Instead of the refs, they will just complain about the incompetency of the reviewers. I do not think we would really be changing anything except making the games slightly longer. I'm sure more correct calls will be made, but as Nightfall stated, the wings will get away with less too.
I have watched all but maybe five wings' games this season, and we have gotten away with our fair share of calls, just as any team does. It is probably not 50/50, but would you really expect it to be? Human error does not work that way. It is no surprise that every fan base has very selective memory when it comes to bad calls - they will always remember the times when they get screwed more than the times when they benefit.
When you are driving in late to work and you hit a red light, do you get irritated and complain? I think most people do, but what they don't consider is how many green lights they made before the red. Selective memory, you only remember the bad things.
