I am so Lost guys

There are a lot of good shows, but nothing is like Lost, sorry, deal with it.

I hear that twin peaks is kind of a mindfuck but I haven't seen it (I know, it's a travesty)

Watch this music trailer. Best show ever.

Nothing is like Lost, nothing can SUCK LIKE IT! :@ :@ :@
After waiting years, that stupid final! I was so angry back then...

Oh no, that show is insanely hard to follow. Season 5 I think is where the actors guild had a strike or something so it is all messed up. And with multiple writers and branching story lines. It is crazy. A really good show, but is hard to keep track of what is happening, season to season.

Hey! I really enjoyed Lost also, but I don't know any other similar shows that had a "catch" for the public.
A good mystery TV series was "FlashForward"(which also features some actors from Lost(Charlie and Penny).. I don't know why, in my opinion it was better than lot of shows out there. And I also think it was intended to fill the gap after Lost(it appeared right after Lost ended).. but maybe it didn't got that much audience.
Anyway.. I'll check back to this post to see if some titles pop-up

Immediately what I thought from the title

I'm so Lost Boys

Did you ever see the X-Files?

These are not really like Lost (nothing is, really, for better or for worse), but you might try out Twin Peaks, The Prisioner (the original british one). Fringe also gets a little bit like it from the second season one, though it is a different beast entirely.
