Baby_Firefly I take it you don't have Showtime don't fret I don't have it either,but I know how you can get your fix.Since Season 3 has been on the air i've been downloading the episodes online. Simply go to Tv Freeload http://forum.tvfreeload.com/index.php they have a Dexter thread where episodes are uploaded.
When the new season starts give it about monday to find the latest episode up.Sometimes the episodes are up within a few hours after airring,but most likely it's monday morning. I don't have Season 4 on dvd yet but I plan on once I have some spare cash (currently have all three seasons).
I know how you feel about the finale I was knocked on my ass because I loved Rita.But I accepted it because for one i'm a fan of Michael C Hall,as well as the whole cast. I haven't seen a show where I love the entire cast since Alias. I watch the show because of the story of Dexter and going by how the current story will be for Season 5.
I highly recommend you check out Season 5 this fall from the trailer,and description by the cast.As well as the producers behind the show this is going to make Season 2 look like a cake walk. I'm a long time fan of Julie Stiles she's talented and beautiful,so i'm curious how her role will be. With Dexter feeling guilt over Rita's death,his Astor feeling anger toward Dexter. Quint being on Dexter's toes as well as the FBI this is going to have his trials from.The Bay Harbor Butcher storyline seem like nothing so i'm pumped for this new season.
