Nah fukk all that.
Hyping up Walt just to not reveal ANYTHING about his powers or what made him special?
Having Michael go through all that shyt and betraying the whole crew to save Walt just to LEAVE Walt and go BACK to the island to get his ass beat a few times and die senselessly? NEVER seeing or reconciling with Walt ever again? That was TRULY the unforgivable portion of this show for me. They SHAFTED the black character.
Having Sun AND Jin die and their child left an orphan?
The ham fisted way they incorporated Jacob and the Man In Black’s backstory and feud.
The Kate/Jack/Sawyer love triangle just being dropped after spending FIVE SEASONS playing that shyt up as a big thing.
NEVER explaining the “rules” or what the fukk the importance of following the guidelines was.
Don’t even get me started on the Flash Sideways shyt from season 6 being Purgatory. That shyt was just groan inducing.
I have so much more I can add it's insane
