Heck yeah. They've been spending the last few episodes blazing through dialogue in attempt to answer as many questions as they can (and sometimes, in the terrible way, i.e. "Why can't Jacob or MIB die?" because Mama Earth said so). But even so, there will be questions unanswered, which is kind of a shame. Killing off Widmore, for example, suggests that we will never know how he got to the island, why he was an other, how he eventually became their leader, and why it was such a big deal for him to come back to the island and "take" it from Ben. *SIGH*
