Dexter is the best show I've ever seen. Ever.

It is very, very, very rare that a show gets better with every season.
Me & my wife started renting it from Netflix two years ago.

We ripped through seasons 1,2,3,4,5.
Each year is better than the previous.

The season 4 finale with Lithgow goes down, in my books, as the greatest TV season-series finale ever.

This is one of those "Everybody I know that has given this show a chance - loves it" shows.
