Ah, I just finished season one tonight. Man, that went by so fast! I LOVED the final twist of the season. This one I can honestly say surprised me. I only figured it out...
The Lt (or was it the creepy guy?) was right, the end was poetic. But not for the reasons they stated. Dexter may be a serial killer but he ain't your cookie-cutter psychopath. He's interesting. I think I may be netflixing season two sooner than I planned.
ETA: More big twists on the way? Cool! I look forward to more creepy, clever, mind-bending fun.
