Who is Arthur Miller? That's the question Dexter and the writers are trying to answer. On the same token, if we figure out exactly who the Trinity Killer is, what do we learn about Dexter? From this episode, I have a pretty good idea. He's completely mentally disturbed, just a total wackjob. While we don't see from his perspective as we do for Dexter, I don't think there is any way the writers can pull him back to normality. In the episode, he was angry at Dexter, happy before visiting his childhood home, pensive while at the house, suicidal, and finally content. Can anyone with such a range of emotional in such a short span not be crazy? Speaking of range, John Lithgow is really doing a great job showing all the emotions.
I haven't reviewed Dexter much mostly because of time constraints, but there is rarely a truly compelling reason that makes me want to review Dexter. The sideplots are exceedingly stupid at times which often take up a good portion of the episode.
"Road Kill" expanded the sideplots with Christy really pushing the limits, spying in Quinn's apartment. From the promo for next week, it looks like her behavior will finally land her in hot water. Deb discovered that someone much shorter than the 6-foot Trinity Killer had shot her. We'll see where this ends up, but twists are always nice.
And now the bad. LaGuerta and Angel is a terrible storyline that should never have started. Now the writers are sticking with it for the long haul. I don't see any way they could make it remotely interesting. Rita and the neighbor Elliot may be in competition for worst story. I loved Julie Benz in Buffy and Angel, but the writers give her such bad material in Dexter. Rita cheating on Dexter does add another angle to the show which is probably the wrong one.
