I continue to be glad that I waited until the series was over to get into it. It's been easier to keep track of the little things between the flashbacks and what is currently going on with the survivors and the others. This season is a really big deal for the series and sees some major changes and shifts.There is also the introduction of flash forwards which means you really have to pay extra attention to what's going on. Of course, the season flows with the same suspense as the previous two. Of course, they still don't tell you what the smoke monster is.Again, this show is like crack and of course Season 3 ends with you yelling at the TV to see season 4. Of course, if you waited like I did to see them on DVD, you can pop season 4 right in!
