Many years later ...
I've finally been watching it, and recently have finished, even though I fell asleep during several of the S6 episodes and need to watch them again.
Not the best of shows to binge-watch, even though the first two seasons hooked me and I very much enjoyed them.
In binge-watching, a number of things came to annoy me, which would make a good Lost drinking game:
1. The number of times the various characters said "RUN!"
2. The number of times various characters said "I promise [insert whatever]."
3. The number of characters who died yet weren't dead, or somehow became someone else.
4. The number of times characters said "If [fill in character or action] does/doesn't do X, everyone will DIE!"
I also got really tired of the character Sawyer/Jim/James having one expression: angry scowl.
No doubt these flaws weren't nearly as obvious and annoying when waiting a week between each episode, but they stand out when binging the series.
