I started watching this show called Dexter and it airs on Showtime.
The premise (without spoilers) is focused on the main character named Dexter Morgan. Dexter is a blood splatter analysis specialist for the Miami Police Department and he is also a serial killer.
It's an incredible show. It's superbly written. And I mean top notch. The plot continuously held my interest. I rented the DVD set from netflix and finished the entire first season in 4 days. I couldn't stop myself. The acting is solid - Michael C. Hall from Six Feet Under (David) plays Dexter. And it gets seriously stomach turning. It's like a whodunnit - silence of the lambs - thriller hybrid.
The second season is about to start next month.

Anybody else who's seen this show will agree with me and if you've seen the first season or part of it let me know what you thought.
