I find peoples opinions on various singers laughable, the truth is people have their favourites and that alone distorts their opinion on anyone else!
Slating one contestant off isn't going to make your "favourite" stand a better chance of winning or change peoples opinion about who they like and don't.
Overrated is a subjective word! Regarding Andrea, he is the bookies favourite & the strongest favourite they have ever had in the history of X factor suggesting there's a lot of people out there who think he is very good & streets ahead of the others.
Does that mean he's going to win? No it dos not! What it means, like him or not, the masses think he's the best contestant.
We all have opinions but ultimately the opinion that counts is the mass opinion, each and everyone's individual opinion counts for very little!
I actually feel most people post negatively regarding other contestants simply because the contestant in question is to them a clear threat to their favoured contestant.
In my eyes most of the posts say a lot more about the poster than they do about the individual they are posting about
