I also only watched Lost after it came on Netflix. The first two seasons were good, though overrated (too many cliches and painfully forced plot points for me). The rest I forced myself to watch to see what happened, just like everyone else.

The ending was terrible, and there are no excuses. The writers had spent 6 seasons making random, wild trout up as they went along just because it sounded cool, with no idea how they happened. This was made blatantly clear at the end, when they... never really resolved anything. The finale redefined "trite" in the dictionary.

Also, I could only take so much of everyone warning everyone else not to listen to the other side or "EVERYONE WILL DIE! THEY'LL KILL EVERY SINGLE PERSON ON THE ISLAND!" before I stopped taking any such threats seriously. Seriously, that is said upwards of dozens of times throughout the entire series.
