'Lost' and 'Supernatural': Have they become the same show? 

have some good points but i don't agree!

i don't agree about that..

I totally don't agree , all this was triggered because the actor who plays Lucifer ( sorry I keep forgetting his name ) has played a character in Lost , what's the big deal !! just admit it that SPN is better than Lost LOL

I don't really agree that they're the same show but they're both very good shows so that's one similarity :) and with Mark Pelegrino in SPN and Lost it's very weird to watch them both especially since he plays sort of mythical, important, mysterious chracters on both. I mean with the previous episode of Lost when there was this scene with him and he appeared out of nowhere I was like "Lucifer! no wait... Jacob!"
But I think they look somewhat the same sometimes because they use a couple of things/actors in very similar ways: the ring of salt/dust protects you from black smoke and the actors who play Lucifer, one of the horsemen and the YED play Jacob, Man In Black/Esau/Smokey/Dead Locke/whatever his name is and the marshal in Lost.
