All the seasons 1,2 and 3 had an awesome story line. It really did grab the audience's attention. My personal favorites are season 1 and 3 however I wish could say the same about season 4. Not that I didn't like the characters or the chemistry between them but just that the story became tangled and tangled to such a point where everything stopped making sense but I am gonna rate 5 stars because of the earlier seasons.
