I disliked Lost and always felt it had a fake (and dishonest) complexity. So many details were introduced, but later forgotten and never resolved.

From the very first episodes, the way they started slowly cycling through each character's backstory, I realised this was going to be a really long drawn-out series that was clearly going to be stretched (and milked) to maximum running length. I'll credit it for it's glossy production look and design. That's one thing that really separates productions today from old: many TV series have the same glossy, high-end look of Hollywood films.
