It's the 10th anniversary of the LOST pilot episode already! A lot of people had issues with the finale of LOST, but I believe it's because many have struggled in putting together the concepts properly.
Please check out this explanation I wrote to be an ultimate guide in understanding the mysteries, mythology, and philosophy of LOST. I promise it will answer any linigering questions you have as well as prove LOST is one of the best shows to ever exist!
