Ok, so I had no problems with the time travel, or with all the eldritch coincidences, or with the compass from nowhere....but this whole "can't kill myself" business is ridiculous.
Do you mean to tell me that if Jack takes a knife and stabs himself in the heart, he will somehow miss his chest or break the blade on a rib? Or if he jumps of a cliff, will a Dharma van happen to be driving by at the bottom with a mattress delivery?
I am having a hard time suspending disbelief on this one. Can anyone make this less painful for me?
