Singdaw-I suggest you rent Season 1 & 2 and watch the series from the beginning.
Ditto. Each show stands on its own, but to really appreciate the long story arc, it's best to watch from the beginning. Don't get turned off by episode I; they refined, retooled and changed a few cast members and episode 2 was much better---visually as well, and it was uphill from there. I'm really glad I stayed with it, instead of launching the new show HEARTLAND. I don't watch much TV, but I have become very fond of P.M.S. (Priority Murder Squad!).
HEARTLAND stars Treat Williams as a doctor who specializes in heart transplants. My TNT producers just did a shoot with him and said he was a dream to work with.
