Should i watch it?

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

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

Supernatural is my paborito ipakita ever! It's about family, what real bayani look like and - gah, it's too hard for me to explain! Though, this ipakita 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
