Season 6 is absolutely terrible. Right from Season 4, I start skipping through parts of many episodes because they were just so boring. Once the time travel nonsense (the sci-fi part) set in, it was so so so so bad. At the 10th episode of Season 6 today, I have decided that I cant take it anymore and I am not going to go through with watching the end of this show. My favorite character is still Kate and Jack, and I used to watch their parts mostly in the last few seasons. John Locke, Sun/Jin and Hugo are the most boring characters as the seasons pass by.
24 WAS FAR FAR BETTER OVERALL!!!! Lost is awesome till Season 3. Then it goes downhill rapidly.
