This is the same show that has a fan base that judges an episode how many zombies get killed. And don't try telling me most people who watch this show don't call and episode boring because there wasn't enough zombie slaughtering. I'm not talking about everyone but there a lot of people who do think that.
The show may have 2-3 seasons left but its going to get very repetivite after the prison arch. I felt the same way about the comic. LOST's story may have gotten too far out there towards the end but at least they made an effort to change it up a bit and you still had a ton of characters who you gave a damn about whether you liked them or not. I can't say the same about Walking Dead.
Not to compare shows, because that wasn't my initial intent, I agree with some of your points regarding both shows, specifically the part about how some fans call an episode boring when there isn't enough zombie slaughtering and how Lost had a lot of characters that people gave a d*mn about.
Now while I feel that the direction of TWD is better for now than Lost ended up with that may change depending on the next few seasons. Only time will tell. I agree that the characters were more important or you felt more for them in Lost, mainly because the drove the show, especially since the overall story didn't really. Yeah the subplots, and season stories were good/great, but the overall show story was weak because the writers didn't know where to take it and if they did it sure didn't work out well; monsters, time travel, good and evil, colonists in different eras, on the island off the island, dream sequences, body possession....yeah the show had it all but for what. Perhaps they didn't think they would get as many seasons, or maybe the writers' strike had a huge part to play. Bottom line was the overall main story suffered.
In TWD the story is good, the plot, the build up, etc. Sure some characters could be fleshed out some more and I'll give Lost the lead on that, but thus far TWD has stayed true to its direction.
Not saying TWD is a better show than Lost, just saying we better not find out that everyone is dead at the end and all this has been for nothing really.
