Misdirection, like any writing technique is only good when written well and used in a way that makes sense within the entirety of the story.
The misdirection of LOST is more akin to finding out at the end of the Sixth Sense that Bruce Willis was actually an alien. Or the Rebellion in Star Wars deciding to team up with the Empire (acting like they never did anything bad to them ever) to battle Satan to keep him from taking over heaven; forgetting completely about the space battles and Force stuff.
I couldn't disagree more.
