We've seen bad calls in sports from Jim Joyce to Don Denkinger, but that's the human element of baseball, mistakes happen.
What's happening with Vic Carapazza is taking things to a whole new level. This man missed the most strikeout calls in the major leagues this year with 86 and has a history of being hugely biased in important games. Check out the following article from the playoffs last year:

In this game, he's been even worse, approaching a +20 missed call differential in favour of the Rangers according to gameday. That's not perfect, but you get the idea.
The fact that MLB continues to run out extremely ineffective umpires that have a history of f***ing up in the playoffs is disgraceful. Everyone in the league office should be ashamed of themselves. One missed call happens. Double digit missed calls in the favour of one team is systematic. It's not 'Canadian bias' as he did the same last year, it's just bad decisions by MLB that ruin playoff baseball for everyone. There are a lot of good umpires in the majors and Vic Carapazza isn't one of them. In fact, he's without question one of the worst and was before this game even started. If this were any other business, he'd be out of a job in a second.
MLB has the umpire quality and pitch f/x information in front of them. Why can't they get this right?
