This was another regressive episode for me.
Once again, we see they are keeping stuff from people for no good reason. Plus now we have people basically saying "so you guys found a bunker...yawn". HELLO! You people are stuck on an island with nothing much to do or talk about. That bunker should have been what everyone on the island is buzzing about.
I don't know about anyone else but I'm also feeling a bit cheated with what they have done with the Hurley character. I liked him last year because he was the 'everyman' character. Not famous, not a professional, not good looking, not exotic...just a regular dude. Then they made him a millionaire, okay whatever. But then he was a guy with mental problems too. Now, based on his recent behavior and speech, I'm getting a definite 'mentally challenged' vibe off him. He's become a simpleton.
Unlike, say, Locke who was a nutjob from the start and STILL is one("my job is making sure the button is pushed, even though there's no reason it should be"), Hurley has been modified in an unsatisfying way.
At least Kate never lets us down.
