A question about Lord of the Rings and Supernatural + others

Okay, so I have two questions, really.

1.) I really want to go see The Hobbit. Thing is, I'm not a LotR fan. So, is it... important, let's say, that I watch the actual movies, or would I understand The Hobbit with no prior knowledge?

2.) I really want to get into Supernatural, but people give me mixed answers with this, so I thought I'd ask here. On a scale of 1-10, 1 being the lowest, how gory is Supernatural? Because I've been told there's hardly any blood, then I've been told most parts, then I've been told some parts. I just want the straight truth. I mean, I don't expect it to be bloodless, but I just want to know what to expect if I honestly try to watch the show.

Anyway, if anyone could answer those for me, that'd be amazing.

How is everyone's holiday going? I wish everyone a happy holidays, and if you don't celebrate anything, then have a happy December xD
