Should i watch it?

Lost is definitely a "One of a kind" show. i've never seen Supernatural, but if te like to think and analyze problems, Lost is the mostra for you. I've watched the entire series twice, and it still amazes me. Hope this helps te with your decision.

I don't even know how to try to describe Lost...there hasn't ever been a mostra like it. OUaT comes the closest because they're the same writers BUT it's not the same mostra At ALL. So, if te like OUaT, there's a good chance you'll like Lost.
And, in my personal opinion, Lost is worth watching just for Sayid ;D

Supernatural is my preferito mostra ever! It's about family, what real Heroes look like and - gah, it's too hard for me to explain! Though, this mostra can be scary at times and there's blood and stuff if that bothers you.

Oh goodness, just try them out and fangirl with me XD
