Not necessarily...It could be a new file that no-one has tried out yet...Once you get used to file sizes and tags you will kind of get the hang of it...
I always check movie files for ratings but the TV series I don't and sometimes I'm the first to rate a file, but as I said it's because of the tag attached...
You can also preview a file to see if it's genuine or not whilst it is downloading, just wait until it's at least 10% downloaded...
