It took me a year to realize that the Dexter on Showtime wasn't the Dexter on Nickelodeon. But once I finally got it straight, wow, Dexter is the best concept for a show ever. The first two seasons were awesome, season three was great, but I'm not too sure how I feel about Dexter marrying Rita (she's annoying) and having kids, instead of making him normal the writers need to expand on the how serial killer aspect of his life.
