Questions, questions, always more questions!

The night that I have been dreading--the LOST season finale--has now come and gone. I've been dreading the finale because I love, love, love this show! And although it was nice to get some long-awaited answers (like WHO is in the coffin...and HELLO! I GUESSED IT WAS LOCKE!!! woohoo for me!), what else do you think happened??? Oh yeah honey--MORE FREAKIN' QUESTIONS !!! Like WHY are they calling him “Jeremy Bentham"? WHY is he not on the island? WHY are they all hating him so much? WHY is Sun trying to link up with the bad guy now? WHY is Benjamin hiding in the freaking funeral parlor? WHAT happened to Jack that he looks like a vagabond now? HOW did Jin get off the island--AND not know who he is or that he is supposed to be married to Sun? WHAT "very bad things" happened on the island after the 6 left, and WHY is Locke blaming it on Jack? WHY would Locke go see Walt? WHAT did Kate go do that Sawyer asked her to do? Why in the world do they have to all go back to the island TOGETHER, including LOCKE'S BODY? And I STILL don't know why there were stinkin' polar bears on that tropical island and last but not least, WHY are they making Sayid wear that ridiculous flat-ironed hair?
