I try not to get into that mentality. Though I think we all fall into it at some point. Otherwise, someone would end up being a bit douche-y for disliking something for the sole reason of being popular. It's best to actually watch something and make judgement for yourself. This is why I'm not one to say that Call of Duty is some abomination against the Forces That Be. I never played any of the games. And you could easily say that the hate for the series is everywhere, just like the hype.
I saw Frozen myself on TV. And honestly, it's okay. Nothing special at all. It's a stereotypical Disney Princess film in many regards. There's people that hype it up as the greatest Disney film, but I just can't see why. On the other hand, just like how the hype has been exaggerated beyond annoyance, so has the hate for the film, to some extent.
But what do I know? I'm just some jerk.
