eh. the 70's shit is still boring. I'm glad that it's finally moving on. I don't really care what they do. I don't really see them being able to change the past (plus, with Dan dead, who the hell knows how to set off the bomb? it's not exactly a matter of just flipping a switch.) and if they did, then we couldn't have a show anymore. what would the last season be, just them going about thier mundane lives?
that being said, the time loop theory was so predictable that everyone saw it coming as soon as the prospect of time travel even came up and it will have effectively resolved nothing and making this whole season just a waste of time filling in the details, that honestly, we already knew about. It has maybe explained two episodes worth of stuff and all of the rest that has been revealed was always there all along for anyone paying attention to the backstory.
What did we really finds out?
That Dharma was there in the 70's doing experiments and that they were at war with the hostiles. We knew that.
That Ben turned against Dharma. Knew that.
That Widmore was the leader of the Others/ Hostiles. Knew that.
That Ben replaced Widmore as the leader and that Widmore had left the island. Knew that.
That Alpert visited Locke as a kid to recruit him for the new leader. Knew that.
That there was an accident with electromagnetism at the Swan that made them have to push the button and it caused the plane crash. Knew that.
That Rousseau killed her crew and Ben took her baby. Knew it times infinite.
All we really learned was how Dan and Miles and Ms. Hawking were conected to the Island. And that the smoke monster is connected to the Temple. We already knew that it assumes the form of people.
We still don't know why the Island is magical, What's up with the smoke monster, Who Jacob is why Alpert is immortal, or how the 06 traveled back to the Island and through time and why.
But there is a glimmer of hope because I have no idea what John Locke is up to and I couldn't be happier about it.
