Since each episode was roughly an hour and there were only 121 episodes, I'm not sure how you could've lost/wasted 6 years on this let alone the two years you claim. Even if you include the nights you stayed awake wondering what the hell was going on, or the time spent researching Lost on the Internet you still wouldn't have wasted two years. While I didn't find this to be the greatest story ever told it was "OK" I feel I wasted an hour every time an episode was what I felt to be useless but it still only added up to maybe a day. Seeing as how I wasn't interested in anything else that was on in that time slot, I don't even feel like I wasted my time watching the Finale. I'd rate it a "meh" maybe. Most of it was twistless, and obvious to anyone that had watched the previous episodes ( or the two hour recap right before it) I knew Sayid and Shannon would get back together, so no I wasn't surprised, and if I had been watching it with my girlfriend, maybe I would've gotten some brownie points for not making fun of her as she cried.
