I gave it a 3.
I watched it three times and my feelings didn't change.
Since this is the final season, I've decided to be more critical. If these episodes are better than any of the other episodes from previous seasons, I'll be harsher than if it was an earlier season. I'm biased against this season.
Positives
Dogan finally giving some answers, but since it was obvious that Jacob brought him to the island, it didn't knock my socks off.
Smokie kicked some butt.
OMG they killed Keamy.

Evil Sayid
Sun was told Jin was on the island alive
Ben is scared
A few good lines from Miles. The comments about Sawyer were gold.
Negatives:
No Sawyer. No Jack. No Hurley. (We did see a brief alt Jack)
Very little Ben.
No Jacob
Sayid's happy ending is Nadia being with his brother.

Where is Richard and the rest of the Others? They said they were going to the Temple.More questions.
The Others just abandoned the temple and Jacob's ways just because Jacob is dead. Do they feel like prisoners being held by Jacob like MIB?
More questions than answers.
Claire didn't go ballistic when she found out Kate took her baby.

Where is Jin? Sawyer?
Why does Dogan want Sayid killed? Because he is a candidate that has the illness? What is the illness?
Keamy wasn't as a bad @## in the alt as he was in the island timeline.
Sayid was forced to return back to being a killer in the alt.
Kate is forced to follow MIB/Flocke, while we all know she will run at the first chance. She hasn't been used much this season except as way to see Sawyer's loss of Juliet.
Sun's weak reaction about Jin being alive and on the island. I thought she would grab Miles and beat him up until he told her more about where he went.
Everyone knew the secret passage but Dogan and Lennon.
What use is the Ash, if it was only Dogan that kept Smokie out? That alone made me rate the episode low. Why build up the ash, have Bram use it, then all of the sudden it's useless.
