The characters are vastly more developed in Season 3. You finally actually get to see Dr. Mike develop into more emotions than confident, fearful and fiesty. She takes on more turns as romantic, despairing, compromising (Dr. Mike?) Some of the episodes are fantastic, especially those revolving around the Cheyenne tribe. One of my favorite episodes from this season is "What is love?" A new "Colleen" is introduced this season who does an even better job than the first Colleen (who was also great) in my opinion. As I said, the best of the first three seasons! It would have been given 5 stars, but there are a couple of throw-away episodes.
