I watched the pilot today, and it was pretty good. Sort of like an X-Files for the current generation. Of course, I'm a little biased because of JJ doing Lost. There are a few similarities, or possible easter egg-like crossovers:
Lance Reddick, who plays Matthew Abaddon in Lost, is one of the main characters. Talk about a creepy dude.
The title graphic uses the same font as Lost.
There's a photo of Sri Lanka towards the end, and in the photo is the octagonal raft that the castaways wash up with, in Sri Lanka.
The most obvious one: There's a scene that I'll call the "Cow" scene, and the song that plays is "Hollywood and Vines" from Lost. I thought that was a little strange, but hopefully it's the last time they cross the music over like that.
