Thought it was ok, not bad, not good. I liked the mysteries so i feel a bit cheated, but not much. What the shazbot! was the deal with the Polar Bears?
Dharma did experiments on them.
The show originally set Walt up to look like he was "special" and caused a few crazy things to happen(appearance of the polar bear).
Later the Dharma experiments were alluded to, and this makes sense.
So was Walt just a normal kid?
The Others kept saying that he was "special". WTF was that all about?
I know Walt was basically meaningless to the overall story, but he was one of the most intriguing characters early on. Really the only nagging character in my mind. Pretty happy with the rest.
