The only problem is have with this season is the whole 1974 thing. When Locke put the wheel back on its axis, they should have been transported back to 2004. There hasn't yet been a good explanation about why they ended up in 1974.
But I know there is a Daniel episode coming up that may shed light on this.
Other thoughts: Ilana is working for Widmore. I don't believe her when she says she was hired by that guy's (golfer) family to find Sayid. How would his family know that Sayid was the killer? They wouldn't. However, Widmore would.
Obviously, the show wants us to figure out who the bad guy is. Is it Widmore or Ben? Personally, I think it is Ben. His murder of Locke convinced me.
I think Ben wants to be the leader of the Others again. Locke is in the way, but he needed Locke to be on the plane to help get them back there. I know that Ben knows that the island has powers (It cured John's paralysis, Rose's cancer, made Jin virile), but I don't believe that he thinks the island and/or Jacob can raise the dead. When he wakes up from the head smack that Sun gave him with that oar, I think he is going to be shocked to see that John is alive.
Highlights of the season thus far: Hurley telling his mother the truth.
Jack's grandfather was cool.
Desmond naming his son after Charlie.
Desmond confronting Widmore.
The lamppost station under the church.
Daniel seeing his mother as a young woman in 1954.
The bomb.
Locke going right into Richard's camp. This explains why Richard was at John's birth in the hospital and why he came to see him at the orphanage in previous season(s). Great stuff.
Charlotte's death. It was handled well.
Seeing young Danielle. We finally got to see her story about her husband and the other members of her team getting sick. Now we know this happened after a confrontation with Smokey. See him rip that guy's arm off? Too cool.
Locke meeting young Widmore on the island.
Locke and Christian in the cavern. It was Christian telling Locke to say hi to his son Jack that actually started to convince Jack that he may indeed need to go back to the island.
Widmore telling Locke that he was "tricked" off the island by Ben.
Abbadon's death.
Seeing Walt.
Ben strangling Locke. I jumped out of my chair and spilled my Dr. Pepper.
Seeing Radzinski. I don't know if you guys remember his name, but he's the guy who shoots himself in the head at the Swan Station. It leaves a big red stain. Desmond asks Kelvin about the stain on the wall. Kelvin tells Des the story; Radzinski went nuts, committed suicide. Also, Radzinski was the guy who drew the florescent map on the wall in the Swan Station that Locke first sees when he is pinned under the door.
Seeing the full four-toed statue even though it was only from behind. It looked Egyptian.
Sayid shooting young Ben.
Questions:Where are Rose, Bernard and the other crash survivors? My guess is that they are in 1977, but were captured by the Others and are now living with them.
Who beat up Ben? Ben calls Jack and tells him that he needs to go pick up Locke’s body at the butcher shop. Why? Because someone beat Ben's ass. Was it Widmore agents? Don’t forget that Ben promised Widmore that he’d find and kill Penny. Did he? Is Penny dead and we just don’t know it yet? Was Ben beaten up by Desmond before managing to escape?
