^ None of the things you mentioned sound remotely interesting.
Well I disagree obviously. LOST had explored and visited various threads in very interesting ways, both in how they facilitated the information and the execution, over the course of its run. I'm sure there were a lot of things that might have sounded silly that based on the clever writing and execution are some of the things that made LOST so great.
But hey if you didn't want to see Dharma, Hanso, possible current day Dharma projects, a better flashback episode to the distant past of the island to see the people who built all the structures we had been teased with over the course of the series or Ilana's backstory and see all the remaining threads not be tied off in an exciting execution a la the last three previous seasons and you would rather have been treated to a full 18 episodes of everyone running around the island episode

after episode, if you would rather have aimless unsatisfying character arcs, quiet plodding contrived scenes masquerading as deep character work, gratuitous namedropping, forced attempts at evoking nostalgia for the series as it wound down, incoherent or flat out dumb threads like Sayid's bi-polar flip flopping between pure evil and good guy martyr, or Sun ramming her head so she could write down stuff to Jack, or Jin being the Resident Kidnapping Plot Device or Hurley nearly getting everyone blown up then everyone thinking that going to MIB who just wiped almost everyone out at the Temple was a good idea or Widmore's arc wrapped up so unsatisfyingly after years of build up, drawn out pacing to stretch the material to cover 18 hours, incomplete answers leaving LOST feeling less like a Satisfying Whole and more like an unfinished story etc etc then you probably did love Season 6.
Though for me Season 6 was a step down in my opinion from the very best of the series and when you say some of the things I mentioned weren't interesting you must not have enjoyed the last few years of the show because those were the kinds of things the series did and you know what the fans loved it.
