I watched Season One based on the recommendations here. Quite enjoyable.

Here are some random thoughts:

1. Locke was great, the best character of the bunch. The island is just one long walkabout for him. Get the idea that the tragedy swirling around him might cause Locke to change his mind about that eventually.

Interesting to see that actor accepted the role on faith. He was told his character would be important, but he wouldn't do much in the pilot.

2. Sawyer is the most entertaining character, the foil for everyone else. His self-loathing is fun to watch.

3. There was perhaps too many fight scenes for my taste, specifically where someone either konks someone else over the head by surprise, or tackles the other person from behind. I read yesterday that the second season has less action than the first, so I assume the writers felt the same way. Probably needed exciting moments in each episode to make sure the audience stayed around, and were more sure of themselves (and the audience) in season two.

4. Loved how each character was tied to another character (at least in some small way) back in the normal world. Those loving touches are what makes series television worth watching.

5. Enjoyed watching the auditions. It looked like several cast members tried out for the part of Sawyer. Included were Jack, Charlie and Hurley (of all people). I got a kick imagining Sawyer played by Hurley...the wry comments...the action scenes...making out with Kate. Funny stuff.
