I didn't think this was one of the better episodes from the LOST barrel. But it certainly was not a bad episode and I don't regret spending 45 minutes watching it.
In fact I thought Rose and Bernard needed an episode to build up their characters. Since we had Rose frequently saying that Bernard was alive in the first season and then had Bernard return alive and mostly well in the second season. Afterwhich we saw them briefly getting together and then that was it. We didn't get to see much except them arguing and walking around the island interacting with the main characters.
Anyways, this may not be a groundbreaking episode. But it wasn't bad.
