This is actually the first time I've ever "cared" as a fan what RT rating a film got. Up until now, I've always been just a user of RT, and it definitely does impact my decision-making, exactly for this reason. If I'm taking my whole family to the movies, I don't want to sit through a POS.
Of course I'm seeing this one, regardless. I know it's weird to even care about what the critics say in that case! But I guess it's human nature to want reinforcement of your own opinions and hope that others will be encouraged to watch it and appreciate the same things I like.
