This show has it all! It has the dramatic elements to keep people in suspense and engaged; it has comedy to keep things light and allow the audience to laugh; it has romance for female demographic; it even has some action (boats blowing up, etc.).
The characters (and therefore actors who portray them) are absolutely delightful; I particularly really enjoy the depth allowed this past season (2), thanks in great part to adding another character, Ben Grogan/Ryan Johnson, to effectively make an already great dynamic even better.
So, if you haven't seen the show: go buy the first season and watch it/or buy episodes off of hulu/iTunes. If you have seen an episode or two, then you are likely among the ranks of MANY who would surely be devastated if this show was not to be renewed for a third season.
Hey USA Executives: RENEW THE SHOW FOR A THIRD SEASON PLEASE!
